Its Carl Zeiss lenses were equipped with built-in motor that allowed auto and manual focus override, while its interchangeable film backs had dark slides and inserts for both 120 and 220 film. The vertical-traveling electronic focal plane shutter has a whopping top speed of 1/4000. According to, it had a TTL metering system with spot and center-weighted modes, three exposure modes (Aperture priority, Shutter priority, and Manual), exposure compensation, and three flash exposure modes (TTL auto flash, TTL auto pre-flash, and manual pre-flash). Also a true-system camera, it featured a range of interchangeable lens and finders, and a body made with materials similar to the Contax RTS 35mm SLR cameras. One of the more modern options is the Contax 645 AF, produced by Kyocera under the Contax brand name from 1999 to 2005, and competed with Pentax 645N and Mamiya 645 AF. Improvements and versions were introduced in other models, including faster top shutter speed of 1/1000 sec, self-timer, removable film backs, TTL flash metering, and style changes.Ĭontax 645 AF Photo from the eBay listing by prosper-nagoya-japan The standard lenses were either the 80mm f2.8 C, the 70mm f2.8 C E, or the 90mm f1.9 C. Accessories included a waist-level non-metered viewfinder, a non-metered pentaprism, and three TTL-metered prisms (CdS, PD, and AE). The film can be pre-loaded in film magazines but cannot be changed mid-roll. The original Mamiya 645 was equipped with an electronically controlled cloth focal-plane shutter with speeds of 8 seconds to 1/500 sec, a mirror lock-up, and selectable multiple exposure. As for the viewfinders, grips, and other accessories, not all of them were cross-compatible. A true system camera, it accommodated interchangeable lenses and viewfinders, and all first and second-generation manual-focus Mamiya 645 cameras used the same lenses and film spools. It was the first Mamiya camera to offer the 645 format and produced 15 exposures on a 120 roll film. For starters, let’s focus on the first Mamiya 645 made from 1975 to 1987.
