Revue 35 FC is styled in a manner suspiciously resembling the LOMO LC-A (or its inspiration, the Cosina CX-2). In contrast to the Cosina's rotating front panel, this one pops upwards to uncover the lens and align the viewfinder window with the eyepiece. While offering a built-in "autosensor" electronic flash, this is otherwise a more basic camera, with a fixed focus lens.
Every film speed setting is related to a fixed f-stop, the size of the diaphragm is observable in the lens when the shutter is not cocked. So there is no exposure metering done actually, but switching on the flashlight at insufficient light; batteries are only required for the flashlight. When the small shifter at the front side is tripped while firing the flashlight the lens is stopped down for a correct lighting from 0.7 to 1.5 meter distance. A chart with flash ranges is printed on the back side of the lens cover, visible when it is opened.
