The Vivitar 35EE is a 35mm rangefinder camera with automatic exposure, rebadged to Vivitar specifications from the 1971 Cosina Cosina 35 in c1978. It is a simpler version of the Vivitar 35ES with a slower lens. The design owes a debt to the Konica C35 and 1974 Minolta Hi-Matic G. It also has a lot in common with the 1977 Mamiya 135 EE. Available in all black, or chrome with black covering, this camera was also rebadged with minor changes as the Chinon 35EE, Revue 400S, GAF Memo ET, Argus Cosina 35 and the Prinz 35E from Dixons. The camera has a 38mm f/2.8 (4 elements, 3 groups) lens with 46mm filter thread and a focusing Range of 0.9m to infinity. It also has auto-exposure via CdS "electric eye" above lens, shutter speeds: 1/30 to 1/650 of a second plus B (only at f/2.8), film speed capability of ISO 25 to 400, flashmatic system with X-sync on hot shoe and PC-socket at 1/25 of a second (Guide number scale on sticker on camera back). The viewfinder has a Brightline frame, parallax correction marks, overexposure and underexposure warning zones, with indicated approximate combined shutter speed and aperture (f/2.8 to f/14) selection shown by needle. The camera originally took a PX625 mercury cell battery. A zinc air equivalent or a higher voltage alkaline button battery can be used. This information taken from camerpedia.
