The Mamiya Universal Press. Designed by a sadist, pleases only masochists.
Any Mamiya R* 67 series camera - RB, RZ, you name it. Like trying to lift two cement blocks with a lens (oddly, often as not a truly excellent piece of glass, which sort of softens this acidic criticism). Likely created by an out-of-work designer for the Folmer Graflex Company.
I didn't know that Don McCullin was a masochist, he uses the Universal Press to create his wonderful landscapes. He also uses the RZ67, and at the age of 83 he doesn't seem to be restrained in any way by the weight of these cameras. I have the "disguised" Universal Press, the Polaroid 600SE and I plan to get an RB67. Wonderful tools for medium format shooters.
