Abstract
A small single lens reflex camera for use with a 110 film format cartridge is provided. The size of the camera body can be maintained at a minimum by an improved view finder optical system which coacts with a movable mirror movable into and out of the photographic path in correlation with the releasing operation of a shutter. A series of reflecting mirrors are utilized in the viewfinder assembly within certain angular design parameters to maintain a compact shape while permitting a highly accurate focusing system. The viewfinder optical system can be assembled as a relatively stationary sealed module unit. The movable mirror is adjustable relative to the optical path to optimize its alignment and calibration focusing of an image on the focusing plate of the module viewfinder.
