The Agfa Optima 1535 Sensor is a 35 mm rangefinder camera manufactured by the German company Agfa in 1977. It has the typical big finder of the Optima series, but on this special model it is combined with a superimposed coupled rangefinder. Shutter speed is controlled electronically by a CdS meter, with speeds from 15 sec. to 1/1000 sec. A special feature of the series is the film advance lever which can be switched to also rewind the film at its end.
