Development

In a report, the Kyocera Optical Devices Division stated existing Contax cameras and Carl Zeiss lenses vere highly appreciated, but users requested a medium format camera for even higher quality. For this reason Kyocera developed a 645 AF system, with the following main features: 1) newly developed lenses from Carl Zeiss 2) empahsis on operability of manual focus besides autofocus 3) high precision film flatness 4) high speed shutter which allows to use large aperture in daylight 5) system configuration which allows for future development 6) operation and automation based on 35mm Contax cameras.[1]

Features

The camera system has a range of interchangeable lenses and finders. The body materials are similar to their Contax RTS 35mm SLR cameras.

The metering TTL system can be used in either spot or center-weighted modes. Exposure modes include AV (aperture priority), TV (shutter priority) and manual exposure. Exposure compensation is available from -3 to 3 stops, in 1/3 steps. Flash exposure modes include TTL auto flash, TTL auto pre-flash and manual pre-flash modes.

The vertical-travelling electronic focal plane shutter design has a maximum speed of 1/4000 of a second. In AV mode: 30 sec to 1/4000, in TV mode, 8 sec to 1/4000. There is a bulb mode and flash sync is also available at 1/125 of a second. There is an electronic self timer with either 2 or 10 second delay.

The Carl Zeiss lenses have a built-in motor which allows auto and manual focus override without having to change lens modes.

The camera uses interchangeable film backs with dark slides, with inserts available for both 120 and 220 film. The back has a film-reminder memo holder. The film loading is automatic with bar coded film and will automatically advance to the first frame. Non coded film requires aligning the backing paper start indicator. Bar coded film ISO can be read automatically with a range of 25 to 5000 ISO. It can also be manually set from 6 to 6400 ISO. The film transport system is motorized, with automatic advance of up to 1.6 fps. It is powered by a 2CR5 battery.
