Description of the Ofunaflex Edit
The Ofunaflex is a copy of the Rolleicord III. The front standard moves back and forth for focusing, and is driven by a knob on the photographer's right, with depth-of-field indications. The film is advanced by a knob on the same side, with an auto-stop device unlocked by pressing the central part of the knob. The position of the first exposure is set by aligning a start mark, and the camera has no red window at all. The round exposure counter window is at the top of the right-hand side.
The viewing hood displays the OFUNA logo and has a built-in sportsfinder and a magnifying lens hinged at the front. It is said that the camera has a manual parallax correction device inside the viewfinder. The name OFUNAFLEX is inscribed on a nameplate above the front plate, with the body serial number sometimes written in small characters below.
The four-element Ofunar 7.5cm f/3.5 F.C. taking lens was designed by Kunitomo Kenji (国友健司) within Ōfuna and made by the company itself. The viewing lens is a View Ofunar 7.5cm f/3.2, and both lenses have bayonet filter attachments. The shutter is a Seikosha-Rapid (B, 1–500), enclosed in a casing with a silver face inscribed SEIKOSHA–RAPID at the top and OFUNA OPT. CO. at the bottom. The shutter cocking lever protrudes under the casing, and the speed and aperture levers are on either side. The selected values are displayed in small windows placed immediately above the control levers: the speed on the photographer's right and the aperture on the left. The release button is at the bottom of the front plate, to the photographer's left, and has double exposure prevention. The position of the PC synch socket varied with time.
Commercial life Edit
The Ofunaflex was advertised in Japanese magazines from June 1953, and was featured in various magazines in July and August. It is said that the company had some difficulty to manufacture the camera, and that the Ofunaflex was not ready for production when it was presented to the press.
The advertisements in Asahi Camera June and November 1953 give the price of ¥30,000. The pictured camera has the synch socket at the bottom of the front plate, on the photographer's right, has no cable release thread in the shutter button and no body serial number in the nameplate. These features are said to be typical of the early cameras; these are called "Ofunaflex I" in some sources, but this designation was not used in the original documents. None of the surviving examples observed so far has these early features, and the only other picture showing them is a photograph of an early Ofunaflex (with lens no.1954x) published in Hagiya, from the album of Kano Masayuki (狩野正之), who was responsible for the assembly and quality control of the Ofunaflex and Ofuna Six from 1954. These pictures possibly show preseries cameras only, and the Ofunaflex was perhaps never sold in this configuration.
The next version is called "Ofunaflex II" in some sources, but this name does not appear in the original documents seen so far. It has the synch socket at the top of the front plate, on the photographer's left, has a cable release thread in the shutter button and the body serial number written in small characters under the OFUNAFLEX name. The earliest advertisement to show these features is that in the December 1953 issue of Asahi Camera, which gives the unchanged price of ¥30,000. The last reported advertisement for the Ofunaflex is dated October 1954.
Some sources give the price of ¥27,000 for the "Ofunaflex II" and mention an "Ofunaflex Automat" with self-cocking shutter, sold at ¥30,000 in October 1953, but this is unconfirmed.
All the known surviving examples have the late features. The only confirmed body number is 28410, where the two digits possibly correspond to Showa year 28, i.e. 1953. Lens numbers are known in the 18xxx, 19xxx and perhaps 20xxx range. Kano Masayuki, interviewed by Hagiya, says that about 500 examples of the Ofunaflex were made.
