The Pigeonflex (ピジョンフレックス, pijonfurekkusu) is a TLR for 6×6 exposures on 120 film. The first model was manufactured by Yashima Kōgaku Seiki (later Yashica). Later models were manufactured by Shinano Kōki (信濃光機). All were marketed by Endō Shashin Yōhin.

All models of the Pigeonflex have f/3.5 taking lenses, focused by movement of the entire lensboard.

The original Pigeonflex — NB not the same as the Pigeonflex I — was the first camera to be manufactured by Yashima Kōgaku Seiki, slightly predating the Yashimaflex (both 1953).[1] It has Tomioka Tri-Lausar 80mm lenses. The shutter is NKS (B, 1–200) with self-timer and flash synchronization. It was advertised in Japanese camera magazines dated March 1953 till May 1954. An early advertisement shows a decorative silver plate behind both lenses, and prices the camera at ¥15,000; a later one shows no silver plate and price the camera at ¥14,800 including case.[2]

After Yashima decided to sell cameras under its own name, Endō switched suppliers, choosing Shinano Kōki who had already manufactured the Pigeon 35. The resulting Pigeonflex IA had 80mm Pigeonar lenses (f/3.2 for the view lens), a cut-out in the front of the finder hood for a sports finder, and an accessory shoe on the photographer's left. The top of the (closed) finder has a circular decoration at the centre. It was advertised in Japanese camera magazines dated March–September 1954.

The Pigeonflex I was a cheaper model, with 75mm Pigeonar lenses and no sports finder. Some examples have an S. Luna shutter. It was advertised in Japanese camera magazines dated July–December 1954, for ¥12,500 as compared with ¥15,000 for the IA.[3]

The Pigeonflex IB has 80mm Tri-Lausar lenses: f/3.2 above, f/3.5 below. It was advertised in Japanese camera magazines dated from August 1954 till April 1955. It has a silver plate behind both lenses.

The Pigeonflex IC is the same as the IB but with Pigeonar lenses (again 80mm, f/3.2 and f/3.5). It was only advertised in Japanese camera magazines dated August 1954, and possibly was never sold.
