I have a number of medium format film cameras in my possession, including a Pentax 67II and Pentax 645N. For cheaper options I have a Yashica A and Holga 120. I recently purchased a Mamiya RZ67 camera, because it had removable backs for swapping film types mid roll, plus it also had format choices like 6x7, 6x6, and 645. I will be getting all 3 backs for it. I purchased a 100-200 Z zoom lens to start, since it was only $60 US dollars plus shipping. I'd like to get a 90mm, but prices are way up there for those. I might also consider the 140mm macro, a 50mm, and possibly a 360mm lens. Anyone use these lenses and how are you liking them? How are people liking the RZ camera today? I still will use my Pentax 67 when I dont have a need to change rolls mid roll. The RZ seems clunkier then the Pentax in use. I havent shot a roll through mine yet, as Im still waiting for my first lens to show up. I must say prices on the RZ have jumped in recent years, but I got mine for $700 US plus shipping (for body, 67 film back, and waste level finder), which I think is a good deal.
