特徴とするカメラの光学系。a photographing lens, a beam splitter into which light transmitted through the lens enters, a photographing optical system that guides a first light flux emitted from the beam splitter to an imaging surface via an aperture stop, and a second light beam emitted from the beam splitter. An optical system for a camera including a finder optical system that guides a light beam to an eyepiece, the finder optical system having a finder shutter disposed near a position where the principal ray of the second light beam intersects with the optical axis; The eyepiece has a fully open position where it does not block the second light beam at all, a half-open position where it partially blocks and reduces the amount of transmitted light, and a fully closed position where it completely blocks and blocks the reverse incident light from the eyepiece. An optical system for a camera, characterized in that the optical system is capable of at least displacing the angle.
