The Ohca is a Japanese 6.5×9cm plate folder made from 1935 by Rokuoh-sha, the manufacturing department of Konishiroku. The name is often spelled "Ohka" by mistake, but the markings on the camera read Ohca.
Description
The Ohca has a metal body, similar to that of the Idea. It is easily distinguished by its focusing worm screw on the photographer's right. The bellows has true double extension. The distance scale is on the left of the focus rails, and there is a depth-of-field table on the camera's left side. There is brilliant finder atop the front standard, and a wireframe finder on the left. The camera has limited vertical movement ability. The name Ohca is inscribed on an oval plate riveted inside the folding bed between the focus rails.
Lens and shutter
The Ohca has been observed or reported with the following lens and shutter combinations:
- Apus shutter (T, B, 25–100), Optor Anastigmat f/6.3 lens;[1]
- Apus shutter (T, B, 25–100), Optor Anastigmat f/4.5 lens;
- Durax shutter (T, B, 1–125), Optor Anastigmat f/6.3 lens;[2]

Commercial life
The Ohca was featured in the December 1935 issue of Asahi Camera and was advertised from November of the same year.[4] The September 1936 advertisement in Ars Camera gives the price of ¥32 with an f/6.3 lens and ¥37 with an f/4.5.[5] The last reported advertisement is dated May 1939.[6]
