PURPOSE: To simply correct parallax by altering only a visual field frame in manual focus mode.

CONSTITUTION: In the manual focus mode, a sectorial gear 59 which engages the rack part 41d of a correction frame moving member 41 is rotated to the position of an index 23 on a camera body side associatively with operation for positioning 'MANU0.3' of a dial 21 instead of 'AF'. Then the correction frame moving member 41 is moved to the right against the drawing force of a tension spring 53, the floor part 35b of a parallax correction frame 35 is positioned at the left end of the flat part B of the cam part 41c of the correction moving member 41, and the parallax correction frame 35 is moved down about a fixed frame, thereby performing the parallax correction as to shortest photographic distance. Thus, only the parallax correction frame 35 is moved in manual focus mode associatively with the operation of the dial 21, so the driving of a lens barrel 13 is never loaded more in the manual focus mode.
