Abstract

PURPOSE:To adjust easily the horizontal deviation of the optical axis by rotating a mirror, by constituting the mirror rotatably round the optical axis between a prism and the mirror. 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 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 parallel with the first optical axis, and an image is seen from an eyepiece part provided on this optical axis. In this case, the mirror 5 is rotated round an optical axis B1-B2 between the prism 3 and the mirror 5, and the prism 3 is rotated round a zoom optical axis A1-A2, thereby adjusting the horizontal deviation of the optical axis and adjusting the inclination of the screen to 0.
