his camera appears to be a less expensive variation of the Zenit Automat. It has an electronically timed metal fan type vertically traveling shutter. It also has a few cosmetic changes and the lower flash jack has been changed into a power jack to allow operation from a remote battery box in extremely cold weather. The camera does not have the built in viewfinder shutter. This camera will not operate without four PX625 or equivalent batteries [2].
