This camera is the medium-size single-lens reflex camera that prefixes the name of "GRAFREX" in America and was exported. The Norita Kogaku took over the Rittreck 6X6 that was made by the Musashino Koki in 68. In '72, it was launched in Japan at last. As for Norita Kogaku the relation is deep with the Tokyo Opt Co. Many of the camera engineers of here were the TOPCON graduate.
The shutter speed is B.1-1/500 seconds and this is a general focal-plane type shutter. This camera keeps the change dials of 120 and 220 film. If you replace the film pressure board to both sides, you are able to use which film. Also, even the switch of a multiple exposure is established and can change easily. Must turn the lever 2 strokes to the winding up of the film. As for the medium-size SLR camera equipped with a quick return mirror the shock of the mirror is very hard, but this camera's shock is very soft.
The penta-prism is able to remove. However, there are only 87% of view rate. This is similar even the Asahi Pentax 6×7. The Norita kougaku made the size of a prism as small as possible. The finder of this camera is able to exchange the waist level and TTL finder.
The standard lens is the Noritar 80mm f2. This is the fastest lens in all of the medium-format SLR camera's lenses. The Norita Kogaku was producing 7 lenses from 40mm to 400mm. The Noritar 70 mm f3.5 keeps the shutter for lens itself.
The accessories shoe is attached to the head of the prism. This is very big size, but the balance with the camera is well.
The auto extension tube is disassembled to three parts. The make quality of this is very wonderful. |
