[Scope of Claim for Utility Model Registration] A finder objective lens unit consisting of a telelens and a wide lens each disposed at the same distance from the rotation center of the objective lens frame is rotatably disposed on a support base by a spindle. In the finder, the finder objective lens unit is rotated between a tele lens use position and a wide lens use position, and the finder magnification is switched between two stages, tele and wide. and two stoppers for adjusting the rotation stop position so that it stops at the wide lens position and the wide lens use position, and the mounting position of the support base relative to the viewfinder main body, on which the eyepiece etc. are arranged, is adjusted between the spindle and the objective lens light. A finder characterized by comprising: a mounting means capable of sliding adjustment only in the direction connecting the shaft;
