Abstract
An optical system for use with a tiltable lens barrel which houses an eyepiece system. The lens barrel is rotatable around an optical axis of light incident upon a reflecting member. The optical system directs light from an objective to the eyepiece system in cooperation with the reflecting member so as to change an axial tilt angle of the tiltable lens barrel and simultaneously to rotate an image rotator disposed in an optical path of light passing through the objective, thereby permitting a tilt of an observation image caused by the rotation of the tiltable lens barrel to be compensated.
