The Mamiya 1000 TTL (1975) is a 35mm single-lens reflex camera built around the M42 screw mount and featuring through-the-lens (TTL) stop-down metering via a CdS photocell located in the viewfinder optical path. The camera represents the mature expression of Mamiya's M42 SLR programme, succeeding the earlier DTL (Dual Through Lens) models and offering a more streamlined metering system focused on stop-down TTL operation.

About this camera
Mamiya's refined M42 SLR with through-the-lens stop-down CdS metering — the 1000 TTL brought accurate TTL exposure measurement to Mamiya's professional-grade M42 line, offering a 1/1000s top speed and a clean mechanical chassis that outlasted the mercury battery era.

Mamiya entered the 35mm SLR market in 1959 with the Mamiya Prismat and developed its M42 line through the 1960s and 1970s, producing the 500 DTL, 1000 DTL, and DTL2 before transitioning to the TTL series. The 1000 TTL replaced the stop-down DTL metering approach with a more refined TTL circuit that read at a single measured aperture rather than the dual-aperture comparative system of the DTL cameras.
In the mid-1970s, Mamiya was competing in the M42 market alongside the dominant Pentax Spotmatic line and the emerging K-mount Pentax models, as well as Chinon and Cosina. The 1000 TTL offered a competitive TTL specification at a competitive price, particularly in export markets where Mamiya had established dealer networks.
Mamiya phased out the M42 SLR line in the late 1970s and early 1980s as it concentrated on medium-format cameras (the RB67 and later the 645 series) and eventually withdrew from the consumer 35mm SLR market altogether.
The Mamiya 1000 TTL represents the refined end of Mamiya's M42 SLR programme — a solid, fully mechanical camera with TTL metering and a 1/1000s top speed that competes directly with the Pentax Spotmatic F. For M42 users, the 1000 TTL offers an alternative to the ubiquitous Spotmatic at lower prices on the used market. The full mechanical operation without battery is a practical advantage for long-term usability, and the M42 mount gives access to the largest legacy lens ecosystem in 35mm photography.
