Cyclon
Rangefinder conversions
The name Cyclon applies to rangefinder conversions for the Gelto and other cameras. The list includes the Arsen, Roico, Molby, Picny, Vero Four and Boltax. These conversions were made by Sugedani Kōki Seisakusho and sold by Sankō-sha and by Matsuzaki Shashinki-ten in 1943 and 1944. They are described in more detail in the corresponding section of the Gelto page.
Camera
The April 1943 government inquiry also has a Cyclon (サイクロン) 3×4cm camera.[1] It is registered as made by Miyamoto and distributed by Sankō-sha, surely the owner of the "Cyclon" brand. It has a Cyclon 50/3.5 three-element lens, also made by Miyamoto, and perhaps a focal-plane shutter.[2]
