Claims
- 1. A camera system having a camera body and a zoom lens associated with the camera body comprising:
- a manual zoom operation member that is operated to move the zoom lens to a desired position between wide and telephoto focal length limits in a manual zoom mode of operation;
- means for manually setting a focal length of the zoom lens;
- means for storing data corresponding to said manually set focal length; and
- means for driving said zoom lens in response to a manual operation during said manual zoom mode to drive the zoom lens to a position corresponding to the stored focal length from a position established by the operation of said manual zoom operation member.
- 2. A zoom lens camera according to claim 1, wherein said camera system is provided with a plurality of modes, one of which is a mode for releasing focal length setting mode so that a setting of a focal length can be possible by said focal length setting means for setting a focal length of said zoom lens.
- 3. A zoom lens camera according to claim 2, further comprising a switch means by which said focal length setting means performs to set a focal length under a condition that said mode for releasing a focal length is selected.
- 4. A camera system having a camera body and a zoom lens associated with the camera body comprising:
- means for driving the zoom lens;
- a manual zoom operation member that is operated to move the zoom lens to a desired position between wide and telephoto focal length limits in a manual zoom mode of operation;
- means for manually setting a focal length of the zoom lens;
- means for storing a focal length set by said setting means; and
- means for controlling said driving means to drive the zoom lens in accordance with the operation of said manual zoom operation member, and to drive the zoom lens in response to a manual operation during said manual zoom mode to a position corresponding to the stored focal length from a position established by the operation of said manual zoom operation member.
- 5. A zoom lens camera according to claim 4, wherein said zoom lens camera is provided with a plurality of modes, one of which is a mode for releasing a focal length setting mode so that a setting of a focal length can be possible by said focal length setting means for setting a focal length of said zoom lens.
- 6. A zoom lens camera according to claim 5, further comprising a switch means by which said focal length setting means sets a focal length under a condition that said mode for releasing a focal length is selected.
- 7. A camera system having a camera body and a zoom lens associated with the camera body comprising:
- means for driving the zoom lens;
- means for detecting the focal length of the zoom lens;
- a manual zoom operation member that is operated to move the zoom lens to a desired position between wide and telephoto focal length limits in a manual zoom mode of operation;
- means for manually setting the focal length of the zoom lens;
- means for storing a focal length of said zoom lens that is input through an operation of said setting means; and
- means for controlling said driving means to drive the zoom lens in accordance with the operation of said manual zoom operation member, and to drive the zoom lens in response to a manual operation during said manual zoom mode and in accordance with the result of a comparison between a value stored in said storing means and a value detected by said detecting means so that the zoom lens is driven to a position corresponding to the stored focal length from a position established by the operation of said manual zoom operation member.
- 8. A zoom lens camera according to claim 7, wherein said zoom lens camera is provided with a plurality of modes, one of which is a mode for releasing a focal length setting mode so that a setting of a focal length can be possible by said focal length setting means for setting a focal length of said zoom lens.
- 9. A zoom lens camera according to claim 8, further comprising a switch means by which said focal length setting means operates to set a focal length of said zoom lens under a condition that said mode for releasing a focal length is selected.
