The 35mm APO Grandagon can cover nominal 6x12cm. In my experience it requires the center-filter, and an aperture of ƒ22, which is disappointing but understandable. If you can try it using the external viewfinder note that it is easy to err in placing the format mask so that it is ever so slightly canted which will make for some wacky outcomes. (Seat the mask so the detent fits correctly.)
