Widelux
The Widelux is a fully mechanical swing-lens panoramic camera first developed in Japan in 1958, by Panon Camera Shoko. There were both 35mm and medium-format models available. Instead of a shutter, the camera has a slit that exposes the film as the lens pivots on a horizontal arc. This pivot allows for some distortion effects not available with traditional cameras. The last Widelux model F8 ended production in 2000.
