Abstract
A camera of the present invention comprises a stationary frame adjustable in position with respect to a camera body in the direction of an optical axis; a cam frame disposed around an outer circumference of the stationary frame to be rotatable about the optical axis and movable in a direction of the optical axis with respect to the stationary frame; a finder optical system provided on the camera body; and a finder optical system driving cam provided integrally with the cam frame for driving the finder optical system. In-focus position adjustment of a photographing optical system of the camera is performed during assembly by moving only the stationary frame in the direction of the optical axis, while the cam frame is kept immobile with respect to the camera body.
