It is set up for a different camera, which I believe Blue Moon also has in the store.
This format results in a huge negative, much bigger and with more detail than any digital camera availeble today (I think). Most digital cameras are set up as "half-frame" or "full-frame" according to 35mm film standards. This gives a 2 1/4 inch square negative, which is huge compared to the 35mm negative. That means it can be enlarged to huge prints.
