SUMMARY

There is a demand for a zoom lens that has a small size and that maintains favorable optical performance by correcting various aberrations. The demand levels are increasing year by year.

The present disclosure has been made in view of the above-mentioned circumstances, and an object of the present disclosure is to provide a zoom lens that has a small size and that maintains favorable optical performance by correcting various aberrations and an imaging apparatus including the zoom lens.

DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

FIG. 1 shows a cross-sectional view and a movement locus of a configuration of a zoom lens according to an embodiment of the present disclosure. Further, FIG. 2 shows a diagram in which the luminous flux is shown together with a cross-sectional view of the configuration of the zoom lens of FIG. 1. FIG. 2 shows, as the luminous flux, the on-axis luminous flux and the luminous flux at the maximum half angle of view in each state. In FIGS. 1 and 2, the upper part labeled “Wide” shows a wide-angle end state, and the lower part labeled “Tele” shows a telephoto end state. Examples shown in FIGS. 1 and 2 correspond to a zoom lens of Example 1 to be described later. FIGS. 1 and 2 show situations where an infinite distance object is in focus, the left side thereof is an object side, and the right side thereof is an image side. Hereinafter, description will be given mainly with reference to FIG. 1 and will be given with reference to FIG. 2 as necessary.

FIG. 1 shows an example in which, assuming that a zoom lens is applied to an imaging apparatus, an optical member PP having a parallel plate shape is disposed between the zoom lens and an image plane Sim. The optical member PP is a member assumed to include various filters, a cover glass, and/or the like. The various filters include a low pass filter, an infrared cut filter, and/or a filter that cuts a specific wavelength region. The optical member PP is a member that has no refractive power. It is also possible to configure the imaging apparatus by removing the optical member PP.

The zoom lens of the present disclosure consists of an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE in order from the object side to the image side along the optical axis Z. The object side positive group GP has a positive refractive power. The object side negative group GN has a negative refractive power. With such a configuration, there is an advantage in suppressing various aberrations throughout the entire zoom range.

The object side positive group GP, the object side negative group GN, the intermediate group GM, and the final group GE each include at least one lens group. All spacings between adjacent lens groups change, and all mutual spacings between lenses in each lens group do not change during zooming. By allowing each of the object side positive group GP, the object side negative group GN, the intermediate group GM, and the final group GE to include at least one or more lens group, there is an advantage in suppressing fluctuation in aberrations during zooming.

In the present specification, a group, in which a spacing between the group and the adjacent group changes in the optical axis direction during zooming, is set as one lens group. During zooming, spacing between adjacent lenses does not change inside one lens group. The term “lens group” in the present specification means a part including the at least one lens, which is a constituent part of the zoom lens and is divided by an air spacing that changes during zooming. During zooming, each lens group as a unit moves or remains stationary. It should be noted that the “lens group” may include a constituent element other than a lens having no refractive power such as the aperture stop St.

For example, each group of the zoom lens shown in FIG. 2 is configured as follows. The object side positive group GP consists of one lens group. The lens group, which constitutes the object side positive group GP, consists of three lenses L11 to L13, in order from the object side to the image side. The object side negative group GN consists of one lens group. The lens group, which constitutes the object side negative group GN, consists of five lenses L21 to L25, in order from the object side to the image side. The intermediate group GM consists of two lens groups including the first M lens group GM1 and the second M lens group GM2, in order from the object side to the image side. The first M lens group GM1 consists of four lenses L31 to L34 and an aperture stop St, in order from the object side to the image side. The second M lens group GM2 consists of three lenses L41 to L43, in order from the object side to the image side. The final group GE consists of one lens group. The lens group, which forms the final group GE, consists of three lenses L51 to L53, in order from the object side to the image side. The aperture stop St shown in FIGS. 1 and 2 does not show the size or the shape, but shows a position thereof in the optical axis direction.

In the example of FIG. 1, during zooming, the object side positive group GP, the object side negative group GN, the first M lens group GM1, and the second M lens group GM2 move along the optical axis Z by changing spacings between the adjacent lens groups, and the final group GE remains stationary with respect to the image plane Sim. In FIG. 1, between the Wide diagram and the Tele diagram, an arrow of a solid line indicates a schematic movement locus during zooming from the wide-angle end to the telephoto end, for each lens group that moves during zooming, and a linear dotted line in the vertical direction is shown for the lens group that remains stationary during zooming.

The object side positive group GP may be configured to consist of one lens group. In such a case, there is an advantage in achieving reduction in size thereof.

It is preferable that the number of lenses, which are included in the object side positive group GP, is equal to or less than 3. The object side positive group GP is a lens group on the object side, and has a large lens outer diameter. Therefore, by adopting a configuration of three or fewer lenses, there is an advantage in achieving reduction in weight.

It is preferable that a lens group, which is closest to the object side in the object side positive group, GP moves during zooming. By adopting a configuration in which the lens group closest to the object side in the zoom lens moves during zooming, there is an advantage in suppressing various aberrations during zooming.

It is preferable that the object side negative group GN includes a lens group, which is closest to the object side and which has a negative refractive power, among the lens groups which have negative refractive powers and which are included in the zoom lens. That is, it is preferable that all the lens groups that are included in the object side positive group GP are lens groups that have positive refractive powers. By adopting such a configuration of the object side positive group GP which is the group closest to the object side, there is an advantage in achieving reduction in size thereof.

It is preferable that the object side negative group GN includes at least four lenses. In such a case, there is an advantage in achieving high performance.

It is preferable that the object side negative group GN includes at least two negative lenses. In such a case, it is preferable that an image side surface of a negative lens, which is closest to the object side, among the negative lenses, which are included in the object side negative group GN, is a concave surface, and an object side surface of a negative lens, which is closest to the image side, among the negative lenses, which are included in the object side negative group GN, is a concave surface. In such a case, there is an advantage in correcting field curvature.

It is preferable that the object side negative group GN includes a lens group in which a biconvex air lens is formed. In such a case, there is an advantage in suppressing field curvature. In the present specification, the air spacing interposed between two lens surfaces facing toward each other is regarded as a lens having a refractive index of 1, and the air spacing is referred to as an air lens. In the example of FIG. 2, a biconvex air lens is formed of an image side surface of the lens L21 and an object side surface of the lens L22, a biconvex air lens is formed of an image side surface of the lens L23 and an object side surface of the lens L24, and a biconvex air lens is formed of an image side surface of the lens L24 and an object side surface of the lens L25.

In the present specification, it is assumed that a lens group, which is closest to the object side and which has a negative refractive power, among the lens groups, which have negative refractive powers and which are included in the zoom lens, is a first negative lens group. For example, in the example of FIG. 1, the object side negative group GN is the first negative lens group. It is preferable that a lens group, which is closest to the object side and which has a positive refractive power, among lens groups, which are closer to the image side than the first negative lens group and which have positive refractive powers, is disposed closest to the object side in the intermediate group GM. In such a case, there is an advantage in achieving reduction in size of the intermediate group GM.

It is preferable that the intermediate group GM includes at least three lenses. In such a case, there is an advantage in suppressing various aberrations during zooming. In order to suppress various aberrations which occur during zooming, it is more preferable that the intermediate group GM includes at least four lenses and it is still more preferable that the intermediate group GM includes at least five lenses.

It is preferable that the intermediate group GM includes at least two lens groups in which a spacing between adjacent lens groups changes during zooming. In such a case, it is easy to suppress fluctuation in aberrations during zooming.

It is preferable that the intermediate group GM includes at least one lens group which has a positive refractive power. In the present specification, it is assumed that a lens group, which is closest to the object side and which has a positive refractive power, among the lens groups, which are included in the intermediate group GM and which have positive refractive powers, is a first intermediate positive lens group. For example, in the example of FIG. 1, the first M lens group GM1 is the first intermediate positive lens group. It is preferable that the first intermediate positive lens group includes at least two positive lenses. In such a case, the positive refractive powers of the first intermediate positive lens group can be shared by two or more positive lenses. Thus, there is an advantage in suppressing various aberrations. It is preferable that the first intermediate positive lens group includes two positive lenses, successively in order from a position closest to the object side to the image side. In such a case, there is an advantage in correcting various aberrations, particularly, spherical aberration. In a configuration in which the first intermediate positive lens group includes at least two positive lenses, it is preferable that an object side surface of a positive lens, which is closest to the object side, among the positive lenses, which are included in the first intermediate positive lens group, is a convex surface. In such a case, there is an advantage in correcting spherical aberration.

A lens group closest to the image side among lens groups that are included in the intermediate group GM may be configured to have a positive refractive power. By disposing the lens group, which has a positive refractive power, at a position closer to the object side than the final group GE, there is an advantage in achieving reduction in lens outer diameter of the final group GE. In particular, by disposing the lens group, which has a positive refractive power, at a position adjacent to the object side of the final group GE, there is further an advantage in achieving reduction in lens outer diameter of the final group GE.

It is preferable that the final group GE consists of one lens group. In such a case, it is easy to reduce the total length of the optical system.

It is preferable that the final group GE remains stationary with respect to the image plane Sim during zooming. During zooming, by causing the final group GE to remain stationary, it is easy to prevent the entry of dust or the like into the zoom lens.

In the example of FIG. 1, the aperture stop St is included in the intermediate group GM. By disposing the aperture stop St in the intermediate group GM having a relatively small lens outer diameter, it is possible to achieve reduction in size of the stop unit. Therefore, it is easy to achieve reduction in size of the entire lens device.

It is preferable that the zoom lens of the present disclosure includes at least one focusing group that moves during focusing. Hereinafter, the group that moves along the optical axis Z during focusing is referred to as the focusing group. Focusing is performed by moving the focusing group. For example, in the example of FIG. 1, the focusing group consists of three lenses L21 to L23 of the object side negative group GN. In FIG. 1, an arrow in a horizontal direction indicating a direction in which the lens moves during focusing from the infinite distance object to the closest object is noted in parentheses below the lens corresponding to the focusing group in the lower part of the drawing. The focusing group functions throughout the entire zoom range including the wide-angle end state, but in FIG. 1, the arrows are noted only in the lower part of the drawing in order to avoid complication of the drawing.

In a case where the object side negative group GN includes a lens group which has a negative refractive power, the entirety or a part of the lens group which has a negative refractive power of the object side negative group GN may be configured to move along the optical axis Z during focusing. The lens group of the object side negative group GN has a relatively small lens outer diameter. By setting the entire lens group or a part of the lens group, in which the lens outer diameter is small, as the focusing group, it is easy to achieve reduction in diameter of the whole zoom lens.

In the zoom lens of the present disclosure, all the lenses in the object side positive group GP remain stationary with respect to the image plane Sim during focusing. By forming another group as the focusing group instead of the object side positive group GP having a large lens outer diameter, it is possible to reduce the outer diameter of the focusing group. Therefore, it is easy to achieve reduction in weight of the focusing group. As a result, the load on the drive mechanism can be reduced.

Further, in the zoom lens of the present disclosure, all the lenses in the intermediate group GM are configured to remain stationary with respect to the image plane Sim during focusing. By forming another group as the focusing group instead of the intermediate group GM in which the diameter of the on-axis luminous flux is large, there is an advantage in suppressing fluctuation in spherical aberration during focusing.

The zoom lens of the example shown in FIG. 1 includes only one focusing group, but the zoom lens of the present disclosure may be configured to include a plurality of focusing groups. Hereinafter, in the zoom lens, the focusing group, which is closest to the object side, among the focusing groups, which are included in the zoom lens, is referred to as a first focusing group. For example, in the example of FIG. 1, the first focusing group consists of the lenses L21 to L23. It is preferable that the first focusing group has a negative refractive power. In such a case, there is an advantage in achieving reduction in amount of movement during focusing.

It is preferable that the first focusing group includes a negative lens that has a concave surface facing in a direction of moving during focusing from the infinite distance object to a close-range object. Such a case is advantageous for suppressing fluctuation in field curvature in a case where the close-range object is in focus. For example, the first focusing group in the example of FIG. 1 moves toward the image side during focusing from the infinite distance object to the close-range object. The lenses L21 and L22 in the example of FIG. 1 are both negative lenses that are concave toward the image side.

It is preferable that the zoom lens of the present disclosure includes a vibration-proof group that moves during image blur correction. Hereinafter, the group, which moves in the direction intersecting with the optical axis Z during the image blur correction, will be referred to as the vibration-proof group. The image blur correction is performed by moving the vibration-proof group. For example, in the example of FIG. 1, the vibration-proof group consists of a second M lens group GM2. In FIG. 1, an arrow, which indicates the downward direction, is noted together with a parenthesis below the lens corresponding to the vibration-proof group in the lower part of the diagram. The vibration-proof group functions throughout the entire zoom range including the wide-angle end state, but in FIG. 1, the arrows are noted only in the lower part to avoid complication of the figure.

The vibration-proof group may be configured to be disposed closer to the image side than the focusing group. By using, as the vibration-proof group, a lens that is positioned closer to the image side than the focusing group and that has a relatively small lens outer diameter, it is also possible to achieve reduction in size of the vibration-proof mechanism. Therefore, it is easy to achieve reduction in size of the entire lens device.

The vibration-proof group may be configured to be included in the intermediate group GM. By disposing the vibration-proof group in the intermediate group GM having a relatively small lens outer diameter, it is also possible to achieve reduction in size of the vibration-proof mechanism.

Therefore, in particular, there is an advantage in satisfactorily correcting spherical aberration and longitudinal chromatic aberration at the telephoto end. By not allowing the corresponding value of Conditional Expression (32) to be equal to or greater than the upper limit value, the refractive power of the object side positive group GP can be prevented from becoming excessively weak. Therefore, it is possible to suppress the amount of movement of the object side positive group GP during zooming. As a result, there is an advantage in achieving reduction in size of the lens system.

$\begin{array}{cc}0.15<\mathrm{fGPw}/❘\mathrm{fGEw}❘<10& \left(32\right)\end{array}$

In order to obtain more favorable characteristics, the lower limit value of Conditional Expression (32) is preferably 0.2, more preferably 0.25, yet more preferably 0.3, even more preferably 0.35, yet even more preferably 0.4, most preferably 0.45, and especially preferably 0.5.

It is preferable that the zoom lens satisfies Conditional Expression (34). Here, it is assumed that a distance on the optical axis from the lens surface, which is closest to the object side in the object side positive group GP, to a paraxial entrance pupil position Penw in a state where the infinite distance object is in focus at the wide-angle end is Denw. For example, FIG. 2 shows the above-mentioned paraxial entrance pupil position Penw and distance Denw. By not allowing the corresponding value of Conditional Expression (34) to be equal to or less than the lower limit value thereof, there is an advantage in suppressing fluctuation in aberrations during zooming. By not allowing the corresponding value of Conditional Expression (34) to be equal to or greater than the upper limit value thereof, it is possible to suppress an increase in diameter of the object side positive group GP.

It is preferable that the zoom lens satisfies Conditional Expression (35). Here, it is assumed that a distance on the optical axis from the paraxial exit pupil position Pexw to the image plane Sim in a state where the infinite distance object is in focus at the wide-angle end is Dexw. However, in a case where the optical member that does not have a refractive power is disposed between the exit pupil position Pexw and the image plane Sim, the Dexw is calculated for the optical member using the air-equivalent distance. For example, FIG. 2 shows the paraxial exit pupil position Pexw. By not allowing the corresponding value of Conditional Expression (35) to be equal to or less than the lower limit value thereof, the incidence angle of the off-axis principal ray on the image plane Sim can be reduced. As a result, there is an advantage in ensuring the amount of peripheral light. By not allowing the corresponding value of Conditional Expression (35) to be equal to or greater than the upper limit value thereof, the total length of the optical system can be reduced.

By not allowing the corresponding value of Conditional Expression (36) to be equal to or greater than the upper limit value thereof, there is an advantage in suppressing various aberrations throughout the entire zoom range.

The example shown in FIG. 1 is an example, and various modifications can be made without departing from the scope of the technique according to the embodiment of the present disclosure. For example, the number of lens groups, which are included in each of the object side positive group GP, the object side negative group GN, the intermediate group GM, and the final group GE, may be different from the number in the example of FIG. 1. Further, the number of lenses, which are included in each lens group, the number of lenses that are included in the focusing group, and the number of lenses, which are included in the vibration-proof group, may be different from the numbers in the example of FIG. 1. The lens corresponding to the focusing group, the lens corresponding to the vibration-proof group, the position of the aperture stop St, and the lens group, which moves during zooming, may be configured to be different from those in the example shown in FIG. 1.

The object side negative group GN may be configured to consist of two lens groups. In such a case, there is an advantage in suppressing fluctuation in aberrations during zooming.

The intermediate group GM may be configured to consist of three lens groups. In such a case, there is an advantage in suppressing fluctuation in aberrations during zooming as compared with a configuration in which the intermediate group GM consists of two lens groups.

During focusing, the entirety or a part of the final group GE may be configured to move along the optical axis Z. According to this configuration, there is an advantage in suppressing occurrence of bleeding. Further, as described above, in a case where the final group GE includes the focusing group, the vibration-proof group may be configured to be included in the object side negative group GN. By disposing the vibration-proof group in the object side negative group GN having a relatively small lens outer diameter, the size of the vibration-proof mechanism can also be reduced. Therefore, it is easy to achieve reduction in size of the entire lens device.

The vibration-proof group may be configured to consist of a lens group which is second from the image side of the intermediate group GM. Alternatively, the vibration-proof group may be configured to consist of only a part of the lens groups which are included in the intermediate group GM.

The aperture stop St may be configured to be included in the final group GE. In such a case, there is an advantage in achieving reduction in diameter of the final group GE.

During zooming, the lens group, which is closest to the object side in the object side positive group, may be configured to remain stationary with respect to the image plane. In such a case, since the total length during zooming is unchanged, it is possible to reduce fluctuation in the position of the center of gravity during zooming. As a result, it is possible to increase convenience during imaging.

During zooming, the lens group, which is closest to the image side in the final group GE, may be configured to move. In such a case, there is an advantage in suppressing fluctuation in aberrations during zooming.

The above-mentioned preferred configurations and available configurations may be optionally combined without contradiction, and it is preferable to selectively adopt the configurations in accordance with necessary specification.

For example, according to a preferable aspect of the zoom lens of the present disclosure, the zoom lens consists of, in order from the object side to the image side, an object side positive group GP that has a positive refractive power, an object side negative group GN that has a negative refractive power, an intermediate group GM, and a final group GE. The object side positive group GP, the object side negative group GN, the intermediate group GM, and the final group GE each include at least one lens group. During zooming, all spacings between adjacent lens groups change, and all spacings between all lenses in each lens group do not change. During focusing, all lenses in the object side positive group GP and all lenses in the intermediate group GM remain stationary with respect to the image plane Sim. The zoom lens satisfies Conditional Expression (1).

Next, examples of the zoom lens according to the embodiment of the present disclosure will be described, with reference to the drawings. The reference numerals attached to the groups in the cross-sectional views of each example are used independently for each example in order to avoid complication of description and drawings due to an increase in number of digits of the reference numerals. Therefore, even in a case where common reference numerals are attached in the drawings of different examples, components do not necessarily have a common configuration.

Example 1

FIG. 1 shows a configuration and movement loci of a zoom lens of Example 1, and an illustration method and a configuration thereof are as described above. Therefore, some description is not repeated herein. The zoom lens of Example 1 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group GM1 that has a positive refractive power and a second M lens group GM2 that has a negative refractive power. The final group GE consists of one lens group which has a positive refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, the final group GE remains stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of three lenses which are first, second, and third from the object side of the object side negative group GN. During focusing from the infinite distance object to the close-range object, the focusing group moves to the image side. The vibration-proof group consists of the second M lens group GM2.

Regarding the zoom lens of Example 1, Table 1 shows basic lens data, Table 2 shows specifications and variable surface spacings, and Table 3 shows aspherical coefficients thereof.

The table of basic lens data will be described as follows. The Sn column shows surface numbers in a case where the surface closest to the object side is the first surface and the number is increased one by one toward the image side. The R column shows a curvature radius of each surface. The D column shows a surface spacing between each surface and the surface adjacent to the image side on the optical axis. The Nd column indicates a refractive index of each lens at the d-line. The vd column shows the Abbe number of each lens based on the d-line. The θgF column shows a partial dispersion ratio between the g-line and the F-line of each lens.

Assuming that refractive indexes for the g-line, F-line, and C-line of a certain lens are Ng, NF, and NC, respectively, and the partial dispersion ratio thereof between the g-line and F-line of the lens is θgF, θgF is defined by the following expression.

$\theta \mathrm{gF}=\left(\mathrm{Ng}-\mathrm{NF}\right)/\left(\mathrm{NF}-\mathrm{NC}\right)$

The “d-line”, “C-line”, “F-line”, and “g-line” described in the present specification are emission lines. The wavelength of the d-line is 587.56 nm (nanometers) and the wavelength of the C-line is 656.27 nm (nanometers), the wavelength of F-line is 486.13 nm (nanometers), and the wavelength of g-line is 435.84 nm (nanometers).

In the table of the basic lens data, the sign of the curvature radius of the convex surface facing toward the object side is positive, and the sign of the curvature radius of the convex surface facing toward the image side is negative. Table 1 also shows the aperture stop St and the optical member PP. In a cell of a surface number of a surface corresponding to the aperture stop St, the surface number and a term of (St) are noted. A value at the bottom cell of the column of D in the table indicates a spacing between the image plane Sim and the surface closest to the image side in the table. The symbol DD [ ] is used for each variable surface spacing during zooming, and the object side surface number of the spacing is given in [ ] and is noted in the column of D.

Table 2 shows the variable magnification change ratio Zr, the focal length f, the back focal length Bf in terms of the air-equivalent distance, the open F number FNo, the maximum total angle of view 20, and the variable surface spacing during zooming, based on the d-line. The magnification change ratio is synonymous with the zoom magnification. [°] in the cells of 20 indicates that the unit thereof is a degree. In Table 2, the values in the wide-angle end state, the middle focal length state, and the telephoto end state are respectively shown in the columns labeled with “Wide”, “Middle”, and “Tele”.

In basic lens data, a reference sign * is attached to surface numbers of aspherical surfaces, and values of the paraxial curvature radius are written into the column of the curvature radius of the aspherical surface. In Table 3, the Sn row shows surface numbers of the aspherical surfaces, and the KA and Am rows show numerical values of the aspherical coefficients for each aspherical surface. It should be noted that m of Am is an integer of 3 or more, and differs depending on the surface. For example, on the sixteenth surface of Example 1, m=4, 6, 8, 10, 12, 14, and 16. The “E±n” (n: an integer) in numerical values of the aspherical coefficients of Table 3 indicates “x10^±n”. KA and Am are the aspherical coefficients in the aspherical surface expression represented by the following expression.

$\mathrm{Zd}=C\times h^2/\left\{1+{\left(1-\mathrm{KA}\times C^2\times h^2\right)}^{1/2}\right\}+\Sigma \mathrm{Am}\times h^m$

Here,

• • Zd is an aspherical surface depth (a length of a perpendicular from a point on an aspherical surface at height h to a plane that is perpendicular to the optical axis Z and that is in contact with the vertex of the aspherical surface),
  • h is a height (a distance from the optical axis Z to the lens surface),
  • C is an inverse of the paraxial curvature radius,
  • KA and Am are aspherical coefficients, and
  • Σ in the aspherical surface expression means the sum with respect to m.

In the data of each table, degrees are used as a unit of an angle, and millimeters are used as a unit of a length, but appropriate different units may be used since the optical system can be used even in a case where the system is enlarged or reduced in proportion. Each of the following tables shows numerical values rounded off to predetermined decimal places.

Example 2

FIG. 4 shows a configuration and movement loci of the zoom lens of Example 2. The zoom lens of Example 2 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group GM1 that has a positive refractive power and a second M lens group GM2 that has a negative refractive power. The final group GE consists of one lens group which has a positive refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, the final group GE remains stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of three lenses which are first, second, and third from the object side of the object side negative group GN. During focusing from the infinite distance object to the close-range object, the focusing group moves to the image side. The vibration-proof group consists of the second M lens group GM2.

Regarding the zoom lens of Example 2, Table 4 shows basic lens data, Table 5 shows specifications and variable surface spacings, and Table 6 shows aspherical coefficients thereof. FIG. 5 shows aberration diagrams thereof.

Example 5

FIG. 10 shows a configuration and movement loci of a zoom lens of Example 5. The zoom lens of Example 5 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group GM1 that has a positive refractive power and a second M lens group GM2 that has a negative refractive power. The final group GE consists of one lens group which has a positive refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, the final group GE remains stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of one lens which is closest to the image side in the object side negative group GN. During focusing from the infinite distance object to the close-range object, the focusing group moves toward the object side. The vibration-proof group consists of the second M lens group GM2.

Regarding the zoom lens of Example 5, Table 13 shows basic lens data, Table 14 shows specifications and variable surface spacings, and Table 15 shows aspherical coefficients thereof. FIG. 11 shows aberration diagrams thereof.

Example 8

FIG. 16 shows a configuration and movement loci of the zoom lens of Example 8. The zoom lens of Example 8 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group GM1 that has a positive refractive power and a second M lens group GM2 that has a positive refractive power. The final group GE consists of one lens group which has a positive refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, the final group GE remains stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of one lens which is closest to the image side in the object side negative group GN. During focusing from the infinite distance object to the close-range object, the focusing group moves toward the object side. The vibration-proof group consists of two lenses which are first and second from the image side of the first M lens group GM1.

Regarding the zoom lens of Example 8, Table 22 shows basic lens data, Table 23 shows specifications and variable surface spacings, and Table 24 shows aspherical coefficients thereof. FIG. 17 shows aberration diagrams thereof.

Example 10

FIG. 20 shows a configuration and movement loci of the zoom lens of Example 10. The zoom lens of Example 10 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group GM1 that has a positive refractive power and a second M lens group GM2 that has a negative refractive power. The final group GE consists of one lens group which has a positive refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, all the lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of one lens which is closest to the object side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group moves toward the object side. The vibration-proof group consists of the second M lens group GM2.

Regarding the zoom lens of Example 10, Table 28 shows basic lens data, Table 29 shows specifications and variable surface spacings, and Table 30 shows aspherical coefficients thereof. FIG. 21 shows aberration diagrams thereof.

Example 17

FIG. 34 shows a configuration and movement loci of the zoom lens of Example 17. The zoom lens of Example 17 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which has a positive refractive power. The object side negative group GN consists of one lens group which has a negative refractive power. The intermediate group GM consists of, in order from the object side to the image side, two lens groups including a first M lens group refractive power. The first M lens group GM1 includes an aperture stop St.

During zooming from the wide-angle end to the telephoto end, all the lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of one lens which is closest to the image side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group moves to the image side. The vibration-proof group consists of the second M lens group GM2.

Regarding the zoom lens of Example 17, Table 49 shows basic lens data, Table 50 shows specifications and variable surface spacings, and Table 51 shows aspherical coefficients thereof. FIG. 35 shows aberration diagrams thereof.

Example 20

FIG. 40 shows a configuration and movement loci of the zoom lens of Example 20. The zoom lens of Example 20 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which group GP and the final group GE remain stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of two lenses which are fourth and fifth from the object side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group moves to the image side. The vibration-proof group consists of three lenses which are second, third, and fourth from the object side in the object side negative group GN.

Regarding the zoom lens of Example 20, Table 58 shows basic lens data, Table 59 shows specifications and variable surface spacings, and Table 60 shows aspherical coefficients thereof. FIG. 41 shows aberration diagrams thereof.

Example 23

FIG. 46 shows a configuration and movement loci of the zoom lens of Example 23. The zoom lens of Example 23 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which group GP and the final group GE remain stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes only one focusing group. The focusing group consists of three lenses which are the fifth, sixth, and seventh from the object side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group moves toward the object side. The vibration-proof group consists of three lenses which are second, third, and fourth from the object side in the object side negative group GN.

Regarding the zoom lens of Example 23, Table 67 shows basic lens data, Table 68 shows specifications and variable surface spacings, and Table 69 shows aspherical coefficients thereof. FIG. 47 shows aberration diagrams thereof.

Example 26

FIG. 52 shows a configuration and movement loci of the zoom lens of Example 26. The zoom lens of Example 26 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which group GP and the final group GE remain stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes two focusing groups. The focusing group on the object side, which is the first focusing group, consists of two lenses which are fourth and fifth from the object side in the final group GE. The focusing group on the image side consists of one lens which is sixth from the object side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group on the object side moves to the image side, and the focusing group on the image side moves to the object side. The vibration-proof group consists of three lenses which are second, third, and fourth from the object side in the object side negative group GN.

Regarding the zoom lens of Example 26, Table 76 shows basic lens data, Table 77 shows specifications and variable surface spacings, and Table 78 shows aspherical coefficients thereof. FIG. 53 shows aberration diagrams thereof.

Example 28

FIG. 56 shows a configuration and movement loci of the zoom lens of Example 28. The zoom lens of Example 28 consists of, in order from the object side to the image side, an object side positive group GP, an object side negative group GN, an intermediate group GM, and a final group GE. The object side positive group GP consists of one lens group which group GP and the final group GE remain stationary with respect to the image plane Sim, and the other lens groups move by changing the spacings between the adjacent lens groups. The zoom lens includes two focusing groups. The focusing group on the object side, which is the first focusing group, consists of two lenses which are fourth and fifth from the object side in the final group GE. The focusing group on the image side consists of one lens which is sixth from the object side in the final group GE. During focusing from the infinite distance object to the close-range object, the focusing group on the object side moves to the image side, and the focusing group on the image side moves to the object side. The vibration-proof group consists of three lenses which are second, third, and fourth from the object side in the object side negative group GN.

Regarding the zoom lens of Example 28, Table 82 shows basic lens data, Table 83 shows specifications and variable surface spacings, and Table 84 shows aspherical coefficients thereof. FIG. 57 shows aberration diagrams thereof.
