Minolta SR-1

The Minolta SR-1 was the second model of Minolta's first series of single lens reflex camera bodies. It was a purely mechanical camera. A 6-lens 55mm-Rokkor had been the standard lens for that camera. When it had been introduced in 1959 several other Minolta Rokkor lenses had already been available, from 35mm upto 600mm focus. At least 5 different versions of the SR-1 had been brought to the market in the following years.

In 1961 a holder for an additional selenium exposure meter has been added to the camera's design. The applyable meters for the SR-1 where connected mechanically with the exposure-time preselector of the camera. When the corect ASA-value of the film had been preselected on the meter, the meter's measuring instrument's scale directly showed the aperture that the user had to select at the lens.
