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 '''645N''' is a auto focus [[medium format]] [[SLR]] film camera manufactured by [[Pentax]] in 1997.

The [[TTL]] exposure meter supports a evaluative, [[center-weighted]], [[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 a metered [[manual exposure]] mode. 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. [[Exposure compensation]] can be in -3 to 3 [[EV]] in 1/3 steps with a dedicated dial. Below this dial is a lever that can set [[Exposure braketing|auto bracketing]]. It can be set in 1/3, 2/3 and 1 EV steps. Using it will fire three exposures. Set this to ISO, and use the up and down arrows to change film speed. A small ML button is provided to lock a meter reading. | The [[TTL]] exposure meter supports a evaluative, [[center-weighted]], [[spot meter]] modes. It has a range of 2 to 21 EV with f/2.8 lens.

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 model, but uses knobs for many of the functions. The previous model required using multiple buttons for adjusting most settings. 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 their 6x7 lenses. The film is automatically advanced with a motor drive. The roll film is loaded onto 120 or 220 film holders. The film loading is semi-automatic requiring alignment of a start mark. The holders have a memo slot as a reminder of film emulsion type. The holders cannot be exchanged mid-roll. There are two tripod sockets, one on the base the other on the left hand side.

645NII
The Pentax 645NII released in 2001, is a revision that supports mirror lock up. There is a custom function settings that can change the camera operations. The data imprinting feature has expanded with more data now including auto bracketing, AE lock, flash, focus mode, AF mode, AF area, and ISO speed. Setting the film ISO is now on the exposure comp dial instead of on the separate surrounding bracketing ring.
custom functions
F1: shutter speed step, single or half. F2: meter timer 10/20/30 sec F3: auto bracketing sequence F4: self timer delay 2 or 12 sec. F5: exposure comp 1/2 or 1/3 step F6: Program shift on/off F7: film counter up or down F8: film count and frame count display in finder. F9: exposure per film. 120 film 15 or 16; 220 film 32 or 33.
