The Mamiya M was first marketed in November 1982. It introduced the Seiko FCM autofocus system, with a focusing range from one meter to infinity. Focus was automatically set by use of a beam sensor. It was possible to lock focus by slightly depressing the shutter button. The 38mm Mamiya-Sekor f/2.8 lens was electronically-controlled by a CdS meter, and shutter speeds were from 1/8 - 1/500. It also had auto film loading and film advance, and an electronic self-timer.
