Mamiya CS system


The Mamiya NC1000, introduced in 1978, was one of the smallest and lightest fully automatic 35mm SLR camera with shutter speed priority system and center-weighted TTL-metering. Manual override was possible allowing full control of every picture taking situation. The camera had electronically controlled focal plane shutter with speeds from 1 to 1/1000 sec. and featured a bayonet-type CS mount with extra wide throat. The Mamiya NC1000s, introduced the same year, added support for interchangeable focusing screens and a film memo pocket on the back cover.

A number of Auto Mamiya-Sekor CS lenses with focal lengths ranging from 14mm to 300mm were available.
