I've read about all of them, from the $300 bronica to the $40,000 H4D. 6x9, 6x7, 6x6 and 6x4.5. Rangefinders, SLRs, TLRs, and everything in between. I own a nikon f100 and 1 nikon d200. I want to get into medium format photography. I am looking for advice on what is the best way to spend $6,000. I love wide angles, will probably need a normal lens, a nice portrait lens and maybe even a macro lens.
