Launched in 1969 with an all-black finish with ageneral dimension body of 7.25 inches × 4.5 inches × 3.75 inches / 18 cm × 11 cm × 9.5 cm; with the standard prism and 105 mm lens would bring the size to 7.5 inches × 5.75 inches × 6.5inches / 18 cm × 14.5 cm × 17 cm. It produces 6×7 images on 120 or 220 roll film. The body is in the style of an oversized 35mm SLR camera. The camera has a dual Pentax bayonet lens mount. The inner mount is typically for lenses with a focal range from 35 to 300mm while the outer mount is for 400 to 1000mm. The shutter is a cloth-based focal plane shutter with speeds of 1 to 1/1000 of a second plus a bulb mode. The camera supports a T mode; to enable this feature the shutter dial has to be set between 1/1000 and X. The shutter release has a locking collar as well as a screw-in cable release connector. For flash synchronisation, there are two PC sockets on the left hand side of the mirror housing, one for FP bulb and another for X electronic sync, at 1/30 of a second. There is no cold accessory or hot shoe built-in. The optional left hand grip does contain a shoe; however this donation did not come with the left hand camera grip. The camera is completely battery-dependent, using a 6V PX28/4LR44 battery. The body does not have a built-in exposure meter. The film transport uses a single-stroke film advance wind lever. The film automatically stops at the correct frame and does not require a red window. The film counter is located on top of the advance lever. Loading film requires opening the film back by pulling the latch on the left hand side of the back downwards. The left side is for the unexposed film, and the right for the film take up spool. The base of the camera has film spool knobs that must be pulled out and aligned with the spools. The film backing paper must be aligned with the start indicators in the film chamber which has two marks one for 120 and another for 220. Roll film type can be selected by a small knob on the right hand side of the camera and by sliding the film pressure plate inside, giving either 10 or 20 pictures. Sliding the pressure plate also changes the film type reminder window on the back. The camera shutter does not work without film. Because of the camera’s standard 105mm f/2.4 lens and prism, it weighs a total of 1760 grams.
