The 645N is a auto focus medium format SLR film camera manufactured by Pentax in 1997. It is based on the previous Pentax 645 model which is a manual focus camera. It is the first medium format auto focus SLR system to be available. Competing cameras such as Contax 645 AF and Mamiya 645AF arrived two years later in 1999.
The Pentax 645N body is very similar to the previous 645, but unlike the previous model which required using multiple buttons for adjusting most settings, this model uses knobs for many of the functions. It is compatible with Pentax 645 series of Pentax-FA (auto focus) and Pentax-A (Manual focus) lenses. Pentax also manufactured an adapter for using Pentax 6x7 lenses.
The electronic vertical-travel cloth focal plane shutter has speeds of 4 seconds to 1/1,000 of a second. The shutter release has a screw in cable release. The electronic flash sync speed is at 1/60 of a sec. A self-timer is available on the shutter release collar, it has a delay of 12 seconds.
The exposure meter supports a evaluative, center-weighted and spot meter modes. It has a range of 2 to 21 EV with f/2.8 lens. Film sensitivity can be set from 6 to 6,400 ISO. The supported exposure modes include P, aperture-priority, shutter-priority and manual exposure modes. Changing modes is simple. To use P mode set the shutter dial and aperture ring to A, set shutter dial to A and desired aperture for aperture-priority, set aperture dial to A and select desired shutter speed for shutter-priority.
The finder uses an interchangeable screens design and can be changed to grid, microprism or split-image screens. The LCD on the top shoulder has indicators for data imprinting, battery, ISO, and the exposure counter. When loaded with film the exposure counter is always displayed even when the camera is off.
It is powered by 6x AA batteries which last approx 130 rolls of 120, or 100 rolls of 220 film.
