The Cosina CT-1 is a 35mm film SLR camera from Cosina Co.
In addition to being sold in its own right, the CT-1 chassis also forms the basis of several SLR bodies including the Nikon FM10, the Canon T60, the Olympus OM-2000 and others, such as the Hanimex DR-1 Super. It fulfilled better-known manufacturers' desire to offer a low-end "no-frills" manual film SLR without having to manufacture it themselves.
Models sold under other brand names known to share the chassis and possibly the whole mechanisms and electronics etc.: Canon T60, Carena CX-300, Chinon CM-7, Olympus OM-2000, Nikon FE10, Nikon FM10, Petri GX-1, Petri GX-2, Revue AC2, Revue SC3, Ricoh KR-5 SUPER II.
The CT-1 chassis is also often, mistakenly, referred to as the basis of some other cameras such as the Yashica FX-3 and the Centon K100 but, although the FX-3 etc. uses a similar chassis, also from Cosina, it's not the same.
