The penultimate model of the Widelux camera line, the F7, was produced by Panon Camera Shoko between 1979 and 1988. The F7 features a fixed 25mm lens set into a rotating barrel that spans a 140 degree field of view. Focus is also fixed with these cameras, featuring a range of about 5ft to infinity.
The camera has three shutter speeds: 1/15th, 1/125th and 1/250th of a second. It makes a negative that measures 24x56mm (a normal 35mm negative is 24x36mm so not quite twice as long). Due to the rotating barrel, Widelux cameras produce images with very even exposure from left to right edge and don't suffer the same exposure falloff seen in flat plane panoramic cameras. At the same time, the rotating barrel introduces distortion of horizontal lines. Horizontal lines below the center will bow down while horizontal lines above center bow up, giving images from this camera a distinct look.

Widelux F7 and Timelessness
Stand in one place and slowly turn your head. During that span of time you may see the seasons slowly passing by, the Earth continuing its inexorably, tireless rotation. The scrolling of the future becoming the present becoming the past. It is a procession that happens seamlessly and without pause.
If you wanted art to imitate life, you could hold a Widelux F7 in your hands. It's 26mm lens is mounted in a barrel capable of rotating through a 140 degree range. The sweep of its lens faithfully recording light onto a curved piece of film, millimeter by millimeter, moment by moment.
