The Minolta Autowide was a viewfinder camera with coupled selenium meter made by Chiyoda Kōgaku Seikō in Japan. The Autowide has a place in history as the second 35mm camera introduced with integral coupled metering, following the Mamiya Elca by a matter of weeks in February 1957.
Concentric rotating aperture and shutterspeed knob-and-wheel on the back of the Autowide were internally geared to the lens aperture and shutter. The meter readout was mechanically coupled to these knobs and also was adjustable through ASA/DIN slots on the meter dial. Exposure combination was found when the meter dial pointer matched the needle driven by the metercell's current. Aperture and shutterspeed readings were read through a magnifying port on top of the camera.
