Cosina CT-1

The Cosina CT-1 is a 35mm film SLR camera from Cosina Co.

Cosina CT1 Super

The Nikon FM10 is based on the CT1 chassis

The Canon T60, another model based on the CT1 chassis

In addition to being sold in its own right, the CT-1 chassis also forms the basis (with variations) of several SLR bodies including the Nikon FM10,^[1] the Canon T60,^[2] the Olympus OM-2000^[3] and others, such as the Hanimex DR-1 Super.^[4] 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,^[5] Olympus OM-2000,^[6][7] Nikon FE10, Nikon FM10,^[5][6] Petri GX-1,^[8] Petri GX-2,^[9] Revue AC2, Revue SC3, Ricoh KR-5^[5] SUPER II (2).

The CT-1 chassis is also often, mistakenly, referred to as the basis of some other cameras such as the Yashica FX-3^[10] and the Centon K100 (which, in itself, is often, incorrectly, said to be an updated Pentax K1000)^[5] but, although the FX-3 etc. uses a similar chassis, also from Cosina, it's not the same.
