This is yet another fine example of craftsmanship by the same person from Japan who made the 24x108 panoramic and the 6x6 fisheye.
The camera is made of two fused bodies of the Konica C35 camera and the aspect ratio is 1:3 , thereby producing a 24x72 sized negative. The lens is a 47mm f/5.6 Schneider large format lens.
