Body
It is designed for portrait, and product photography. The right hand side of the body has the shutter speed dial, film wind button, along with a mode switch that controls single, continuous and a multiple / instant film exposure modes. The bottom part has a remote control socket, mirror control, sync test, and shutter release. The left of the camera body has the battery holder and battery unlock switch. The front standard has release knobs for rise/fall, tilt, shift and a swing lever. The camera is powered by a rechargeable 7.2 volt Ni-Cad battery.
It uses interchangeable lenses with bellows type focusing. The bellows can also be changed with a wide angle or close up type. The lenses are mounted on a lens board type system which allows for movements on the front standard similar to view cameras. The front sits on a rail that connects to the main camera body, two knobs on either side control the focusing. The standard lens is a EBC Fujinon GX 135mm f/5.6. An 82mm filter thread is standardized. The shutter is a electronically controlled and located within the lens. It has speeds of 8 seconds to 1/400 of a sec plus a bulb mode. The lenses have controls for aperature and a depth of field preview lever. The cocking of the shutter is automatic. Flash sync is at all speeds and can be connected to the camera body PC socket on the right hand side of the body or to the hot shoe on the front standard.
Film transport
It uses interchangeable, removable film holders mounted on a rotating back. Film is loaded onto inserts. The film transport is motorized with a automatic film loading system. This allows automatic advance of film, as well as film loading without exact alignment of the start indicator. A chime alerts when reaching the last frame. To protect against loosing exposures when changing holders it uses a interlocking dark slide system. A dark slide holder is built into the back. The film holder is powered by a 3.6v lithium ½AA battery. This battery is used when the holder is detached from the body. A memo holder is on the back as a reminder of the type of film loaded.
Finder
The viewing system can use interchangeable finders as well as focusing screens. The standard screen has a matte surface with a microprism center. The standard finder is a folding waist level type. It has a magnifier with 2.5x magnification and interchangeable with various diopters. AE finders are available with a built-in exposure meter. It provides aperture priority TTL metering. A orientation indicator is visible in the finder when the rotating back is in the horizontal position.
