Abstract

PURPOSE:To adjust the single-lens reflex finder easily for the deviation of the optical axis, the inclination of the screen, etc., by installing the reflective mirror of a mirror to pass through the second principal point of a view finder master lens. CONSTITUTION:A part of the light condensed by a master lens 2 of a camera has the optical axis bent at about 90 deg. by the reflection of a prism 3 or the like and passes through a view finder master lens 4 and has the optical axis bent again at about 90 deg. by a mirror 5 to be in parallel with the first optical axis, and an image is seen from an eyepiece part provided on this optical axis. In this case, since the reflective face of the mirror 5 is installed to pass through the second principal point of the view finder master lens 4, the inclination of the screen as well as the deviation of the optical axis are adjusted by rotating the mirror 5 round a VF optical axis C1-C2 or rotating the prism 3 round a zoom optical axis A1-A2.
