The Pentax 645 supports both 120 and 220 film formats, requiring different film inserts. A standard roll of 120 film will get you 15 exposures, producing 6 × 4.5 cm negatives with distinctive negative borders.
It features a focal-plane shutter with speeds ranging from 15 seconds to 1/1000th of a second, plus a bulb mode. Its built-in light meter has never let me down, and all exposure information and settings are displayed and adjusted via the LCD on the top plate.
While the camera does not have autofocus, it includes a motor drive that automatically advances the film be it with an embarrassing loud noise. If you shoot portraits expect you models to look supprised or even shocked the first time you press the shutter.
Its integrated right-hand grip is an unusual design choice, but it provides a surprisingly ergonomic and comfortable shooting experience. Not a luxury for such an heavy camera. The grip houses six AA batteries that power the camera.
Also this camera has a pc sync port wich allows the use of external flash units in the studio. The Pentax 645 has a maximum sync speed is 1/60 sec.
