Olympus Pen EES
Manufactured from 1962 to 1968 by Olympus Optical Co. in Japan. As a half-frame, it took 72 “portrait” images on a 36 exposure roll of 35mm film. It was an improved version of their EE model. It had a selenium cell controlled automatic exposure mode for either 200 or 160 ASA film, or you could set the shutter speed or you could set the aperture for X-sync flash pictures—all with the same ring around the camera lens! It featured a shutter lockout—if the cell didn’t detect enough light for the setting selected, the shutter would not fire. It had a 30mm f/2.8 lens with zone focusing. And to make it easier to load the camera, the entire back and bottom of the camera was removed to change film.
