Japanese medium format 6x6 SLR system which consisted of a single camera - the Rittreck 6x6 - designed and produced by Musashino Kōki K.K. in 1968 and distributed by Rittreck Shōji, a separate trading company. For export, the camera was sold under the name Warner 66. Already in 1969, Musashino Kōki K.K. went bankrupt, and the production of the camera was handed over to Norita Kogaku under the new name Norita 66 (or Graflex Norita, in the US market).
Norita 66 was a unique medium format camera built for SLR eye-level fast and easy action. The camera was slightly larger than comparable 35mm cameras in weight and dimension. It was conceived and designed keeping in mind the rigid requirements of the professional photo-journalist, industrial photographer and advanced amateur.
Focal plane shutter speeds were in three groups: a) Bulb to 1/30th second, b) 1/60th to 1/500th second and Bulb to 1/15 second, and c) electronic flash (strobe)-(X)-at the fast 1/40th second and Bulb to 1/15th second. A special front leaf shutter lens provided strobe capabilities up to 1/500th of a second.
A super-speed 80mm F/2 lens interchangeable by a breeachlock bayonet mount was supplied as standard equipment. A full range of lenses was available from the super-wide 40mm to the telephoto 400mm. All lenses were produced by Norita Kogaku from the beginning: initially under the name RITTRON for the Rittreck 6x6, later NORITAR for the Norita 66.
