(btw, does anyone know whether 36x48mm being exactly twice the 24x36mm 'full-size' chips with 35mm cameras is a coincidence?) (or: is large format typically 72x48, or 96x72mm)
Medium format is:
6x45 = 56mm x 41mm 6x6 = 56mm x 56mm 6x7 = 56mm x 66mm
and so forth up to 6x17 and 6x19 backs. So the Mamiya ZD isn't full frame medium format, but it is double-frame miniature format.
Large format is typically 4" x 5" and larger. That's about 10cm x 12cm.
