The CH is a Japanese strut-folding camera taking Sweet-size plates (about 4×5cm), patterned after the British Ensignette. The camera is known from a single surviving example pictured in Sugiyama.[1] It was made by an unknown company, certainly in the 1920s. It was surely distributed by Misuzu Shōkai, which is known to have used the CH brand at a later period.

The CH camera has a fixed-focus lens, a brilliant finder inside the front standard, and a simple shutter with Time and Instant settings selected by a lever at the front. The front standard has the words Achromatic lens above the lens, the model name "C.H" below and New PATENT CAMERA. at the bottom right.
