Abstract
In a single lens reflex camera, the shutter base plate is provided with a recess in which the reflecting mirror is mounted. This permits the mirror to be closer to the film plane and hence permits the imaging plane, prism and viewing lens of the view finder to be closer to the optical axis of the camera lens, thus reducing the overall size of the camera.
