As its 16mm cameras had been growing increasingly large through the addition of more features, Minolta introduced a new and much smaller model, the 16 MG, in 1966. It lacked automatic exposure, but included a light meter and match-needle that were almost as easy to use and offered the added bonus of manual exposure control. The aperture and shutter speed were set at the same time using a single "exposure" dial. The meter was a selenium unit, which did not require a battery and hence allowed the camera to be made smaller. The 16 MGS of 1970 was similar but used single-perforated film, which allowed the negative size to be increased and picture quality improved.
