When I found the Olympus OM - 1 35 mm Film SLR Camera, there was a roll of film already in the camera. The film advanced properly when actuating the mechanism, but I did not try to develop the roll. It was removed and disposed of for listing photography purposes. Therefore, I must describe this camera as UNTESTED.

One of the photos was taken through the viewfinder.

The lens is common for this model, a G. Zuiko Auto - S 50 mm f1.4.
