Once the holder is locked, and you press the shutter button, the camera will automatically wind the film to the first position. The film travels vertically instead of side to side. You load and pre-thread the film outside of the camera in the film holder and then insert the film holder into the camera. There are separate film holders for each type of film. It has contacts to support Pentax dedicated flash units in TTL mode. There is no built-in selftimer on this camera.Ī hot shoe for attaching a flash sits on top of the view finder. A stop down lever for viewing DOF is on the right side of the camera body. There is control for +/- exposure compensation. Exposure modes supported are B, M, Aperture Priority and Shutter Priority. On top of the camera body is a cluster of buttons and an LCD display to change and display exposure mode, ISO setting, etc. The focusing screen can be changed for different photographic need. I have a large eye cup on the eye piece and optionally a magnifying eye piece can be attached to it for work requiring more precise focusing. There is a dioptre adjustment on the eye piece. One corner of the view finder has a red LED display for metering infomation. I find it adequate for my kind of work, which is landscape and nature. The incorporation of the grip handle allows me to hand hold it like an SLR, wh ich I thought was a great advantage over other MF box cameras. It incorporates a built-in grip with shutter release and an On/Off switch. The body is a unique box shape, deeper than wide, unlike SLRs.

(The newer 645N even has the auto focus mechanism added to the mount system)

It rivals the modern DSLR mounts that have contacts for aperture auto mode. It uses the Pentax 645 lens mount system, which upon my examination, is quite an advance mount. The operation of the camera is excellent too. It is quite heavy (lighter than my 67ii), solid construction and clean lines make the appearance very appealing. The construction of the camera is top notch. Having owned modern digital SLR cameras, going back to this is like re-discovering the good old days.
