Template:Japanese postwar 6×6 TLR (A–L) The Alfaflex (アルファフレックス) is a Japanese 6×6 TLR made by Alfa Camera Seisakusho from mid-1952 to early 1954.[1]


The Alfaflex is a regular copy of the Rolleicord. The focusing is done by moving the front plate back and forth and the film advance is controlled by red window. The focusing and film advance knobs are on the photographer's right, and the focusing knob is surrounded by a depth-of-field scale. The back has a single red window in the middle, protected by a vertically sliding cover. There is a magnifying lens in the viewing hood but no sportsfinder. The name ALFAFLEX is inscribed on a stepped nameplate above the front plate, and the company name ALFA or ALFA OPTICAL CO. is sometimes written in small characters underneath.[2] The leather case is embossed Alfaflex at the top.

The shutter is a TSK giving B, 1–200 speeds. The release lever is directly placed under the shutter casing and the synch post is buried in the front standard at the bottom. No self-timer is visible. The shutter is marked TSK on the speed rim and TOYO S.K.CO on the shutter plate, and it was surely made by Tōyō Seiki Kōgaku.

The lenses are Alfa 7.5cm f/3.5 or S. Cosmo 7.5cm f/3.5. The Alfa are engraved ALFA 1:3.5 f=7.5cm No.xxxxx and the S. Cosmo are engraved S. COSMO 1:3.5 f=7.5cm ALFA Opt. Co. No.xxxxx.

Commercial life[]

The Alfaflex was featured as a new product in the July 1952 issue of Ars Camera.[3] It was offered along with the Cosmoflex in an advertisement dated March 1953, with S. Cosmo lenses.[4] No price was indicated and the camera name was simply "Alfaflex".

Some recent sources mention an Alfaflex I and Alfaflex II, certainly differing by the lens type (Alfa or S. Cosmo), but it is not sure that the distinction was made at the time.[5] The Alfaflex was eventually superseded by the Cosmoflex, a slightly improved model.

  5. Sugiyama, item 2050, presents an example with S. Cosmo lenses as an "Alfaflex II". Lewis, p.80, briefly mentions an Alfaflex I and an Alfaflex II. This page at Japan Family Camera says that the "original model" has Alfa lenses and that the "Alfaflex II" has S. Cosmo lenses and a self-timer. However no self-timer is visible on the cameras observed so far with S. Cosmo lenses.
