PURPOSE: To reduce a parallax at the time of macrophotographing by allowing an optical element for correcting the parallax to advance into a finder optical system at the time of macrophotographing by bending a finder optical axis in the optical axis direction of a photographic optical system.
CONSTITUTION: When a cam ring 14 is driven by a zooming motor, and from the macrofeeding-out section 20f of its zooming cam groove 20, a macroend fixing section 20g is engaged to the roller of a front group frame, the front group frame is further fed out of a telephote end and goes into a macrophotographing area. In such case, as for a cam plate 53, a subdriving pin 70 of a deflection angle prism operating plate 67 is engaged and moved from the projecting motion section of its parallax correcting cam groove to a projecting position fixing section. As a result, the deflection angle prism operating plate 67 is operated, and a deflection angle prism P1 is turned in an optical path by the force of a torsion spring 75. Therefore, the parallax at the time of macrophotographing can be reduced.
