Semi Renky
The Semi Renky is a Japanese 4.5x6 camera that looks very much like an Olympic. It was apparently made by a company named Rengo (Rengō Kōki, 連合光機). There were at least two versions:
- Semi Renky with bakelite body, 25-50-100-150-B-T shutter, f/4.5 lens and accessory shoe, RengoKoki and Tokyo on the helical ring, Semi Renky on the shutter plate and Semi Renky in capital letters on a body plate (similar to the plate marked The Olympic Camera Workson the Olympic cameras), illustrated here at Japan Family Camera
- New Semi Renky with a different metal body, same shutter, Tenobar Anastigmat 75/4.5 lens
- marked RengoKoki (and Tokyo?) on the helical ring, New Renky on the shutter plate, no body plate (illustrated in McKeown)
- marked New Semi Renky and Rengo Koki Tokyo? on the helical ring, Semi Renky on the shutter plate, no body plate (observed at ebay auction)
