PROBLEM TO BE SOLVED: To provide an in-focusing control mechanism for a camera capable of obtaining the same focusing effect as in the conventional manner, and realizing the common use of a main body in a lens shutter camera and an AF function for general interchangeable lenses in a system camera by automatically adjusting a film surface. SOLUTION: A film holding part 20 including a film aperture part 17 is made a movable part, and consituted to be moved in parallel with an optical axis direction while holding the film 23 in the movable part. By setting a starting position in the moving control of the movable part, the movable part is restored to the control starting position interlocked with winding the film. The movable part is energized in a control direction by springs 11 and 13 and restored and locked at the starting position against the resistance of the springs 11 and 13 simultaneously with feeding the film, which is performed every time photographing is finished. |
