Mamiya 645 Pro with Mamiya-Sekor Zoom C 55-110mm f4.5 brand_Sigma and interchangeable mounts (other mountsThe Mamiya 645 Pro is a relatively modern medium format SLR with a streamlined design, a well integrated TTL metering prism, and a large library of Mamiya 645 lenses to choose from. This 645 Pro includes the slightly bulky but pretty darn useful 55 110mm f4. 5 zoom lens, roughly equivalent to a 35 70mm lens on 35mm.
