The Koniflex is slightly unusual in its 85mm lenses (rather than the customary 75–80mm). The View Hexar viewing lens is f/3.0 (and, thanks to a condenser, the screen is fairly bright); the taking lens is a Hexanon f/3.5 with five elements in three groups, said to be similar in design and characteristics to the Voigtländer Heliar. The entire lens assembly moves in order to focus. One can focus "beyond infinity" in order to retract the lens assembly further within the body; this not only saves some space but also locks the shutter. (When focusing, there is a tangible "click" as one passes the infinity setting, so there is little or no danger of accidentally misfocusing.)
The shutter is a Seikosha-Rapid (B, 1–400).
The Koniflex uses semi-automatic film advance (unusually, for either 120 or 620 film); you align the start mark against two red dots, close the back, and use a knob on the right to wind until winding stops as "1" appears in a small window on the left; after cocking and firing the shutter (below and to below and to the left of the taking lens respectively), you press the button within the wind knob, release it, and wind on till stopped as "2" appears in the window — and so forth.
An accessory shoe is on the left. The finder hood contains a large magnifying glass and the front of the hood can be flipped out of the way to create a sports finder.
The original Koniflex (sometimes referred to as Koniflex I) was released at the end of 1952. It has a Kodak-style flash terminal. Its dimensions when closed are 145(H)×98(W)×104(D) mm., and it weighs 960g; it takes 39.5mm screw or 40.5mm push-on filters. It was priced at ¥47,000, unusually high for a TLR.
Minor improvements were made in mid-1955: baffles to cut internal reflections, a double exposure lock (with override at the front centre of the left-hand side), and an improved catch to hold the back closed. The flash terminal is now PC. (This camera is now often referred to as the Koniflex II; Konishiroku did not call it this at the time, and the nameplates of both versions simply say KONIFLEX.) With the release of the improved version, the price of the original was dropped to ¥41,500. Later examples of this improved version had further refinements to the finder.
A small number of the later Koniflex models was exported to north America and sold, as a Tele-Koniflex, together with an attachment lens set. The taking lens is a Hexanon 135/4.5; the viewing lens a View Tele-Hexar 135/4. The lens set has the same serial number as the body for which it was intended. (The attachment lenses were first displayed in October 1954 in an exhibition of future products held by the company in three department stores in Tokyo.)
The Koniflex was the only 6×6 TLR that Konishiroku ever sold. (It had created a prototype Sakura-flex in 1939.) Stock of the Koniflex ran out in 1958, by which time its price had sunk to ¥32,000. Total production was less than 13,000.
