No, I meant typical sensor sizes for 35mm, 6x6/7 & 4x5"....;))

Actually, Mamiya lists a conversion factor of 1.25x, which is the
best in the industry, apart from 1.0 of course....:))

On this Kina, I also read about a 5x12 camera.
My inititial association was 5x12cm, like the Noblex swing-lens
panorama camera....yet it was 5x12"....:))
(along with a 7x20", all from China, quite interesting industry shift
actually (the large-format sector is growing, worldwide, although
nobody knows for how long, cq whether this is a temporarily anti-
sentiment to digi)
Oh, and a 6x24cm camera is also in the making (a swing-lens 5x20cm
already existed, this one is fixed/rigid)....again Chinese, for 1/3rd
of Linhof/Gilde price. Gotta love those Chinese....:))
