This camera is a twin-lens reflex camera released in 1953 by Yashima Optical Co., Ltd. (later Yashica), and is a rather rare camera, considered the original Yashicaflex. Yashima Optical Seiki began providing OEM twin-lens reflex cameras under the name "Pigeonflex" to Endo Shashin Yohin Co., Ltd. in 1953, but in the same year, they began parallel sales of this "Yashimaflex" under their own brand, with the same design. However, four months later, they released the "Yashicaflex B (early model)" with a changed shutter and model name, and the manufacture and sale of cameras bearing the name "Yashimaflex" ended in 1954, resulting in a small number of units produced and sold. Consequently, working examples are rarely seen today. Both lenses are Tomioka Optical's Triroza 80mm F3.5, and the shutter is a NKS B, 1-1/200 second, made by Nihon Kosoiki Seisakusho (later Talon). The product's finder lid is slightly stiff to open and close due to aging, but it functions well. The body has quite a few scratches and dirt. The leatherette is partially peeled off, but it remains in relatively good condition for its age. The finder mirror was quite cloudy, so the surface mirror was cut out and replaced, but it's a DIY job. By the way, the material cost of this surface mirror was about 3,000 yen. The finder has become considerably brighter, but the finder of a twin-lens reflex camera is not that bright even when new. It is equipped with a magnifying loupe and a sports finder (through-view finder) function. The lens has cleaning marks on the front element surface that could be mistaken for spiderwebs. The coating is also considerably peeled off, but there is no haze visible. It may result in slightly soft focus in actual shooting. There are no problems with the operation of the shutter and aperture. Overall, it is at a level that can somehow be used for actual photography. I think this camera has more value as a historical document for understanding the history of cameras than as a tool for photography.
