PURPOSE:To surely position an optical element even when the optical system of a finder is switched, by guiding or limiting each optical element by means of the same member. CONSTITUTION:A finder housing 60 which is formed of a synthetic resin in a finder containing section 1a in one body with the section 1a is firmly provided in the section 1a and a finder optical system is supported, limited, and guided by the finder housing 60. When a focal length selecting member 2 is witched to a wide-angle position for taking a wide-angle photograph, a switch SW2 is turned off and a main optical system 3 is displaced from its filed position to its extended position. Therefore, the absolute and relative accuracy of the guiding and limiting parts can be improved extremely.
