Mamyia 35mm SLRs were produced with many different screw and baynoet mounts. Here's a nice set of Mamyia Sekor CS lenses, along with the corresponding Mamyia NC1000 and NC1000S cameras.

While most photograpers know Mamiya for their medium format cameras - among them the "small" Mamiya 645,  the famous RB67/RZ67 series, and the 6x6 and 6x7 rangefinders - the company was very active in the field of 35mm SLRs as well:

Mamiya TL and DTL series (M42 screw mount; introduced 1968): classical M42 cameras with stop-down TTL metering using CdS cells

Mamiya XTL (new Mamiya Sekor ES bayonet mount; launched 1971): Automatic exposure coupled with switchable "average" and "spot" TTL metering

Mamiya MSX and DSX series (Mamiya Sekor SX lenses with modified M42 screw mount): TTL metering with open aperture ("spot" or "spot/average" depending on model)

Mamiya NC1000 (new Mamiya Sekor CS bayonet using the same aperture control mechanism as the M42 lenses): Released in 1978. Previous M42 lenses may be used with a spcial adaptor; previous Sekor ES lenses do not fit.

Mamiya ZE and ZM series (new Mamiya Sekor E bayonet, later modified to the Mamiya Sekor EF bayonet): Introduced in 1980, using a strongly modified bayonet with electronic contacts. The Sekor CS lenses can be mounted, but their use is limited to the stop-down mode.

This rapid succession of four different camera mounts within just 12 years was simply too much.
