Well Stone, With Tech Pan, it's almost like running real leaf of gold thru your camera. You have to fill report card and tax return for every single frame of it. Hasselblad 70mm magazine is very, very similar to A12, just bigger. And with Hasselblad there is not easy double exposure unless you take magazine off and then wind the film and cock the shutter. On RZ, do you wind film with lever on magazine or with RZ crank on the body?
