Mamiya 45mm f/2.8

{"overview":"The Mamiya 645 45mm f\/2.8 is a moderately wide-angle prime designed for the Mamiya 645 medium format SLR system, where its 45mm focal length covers a noticeably broader field than the 80mm standard lens. With only a single tracked result the price band is narrow, and clean examples with their caps and a clear front element typically sell for a small premium over scruffier copies. Buyers should remember these figures are wholesale auction hammer levels rather than dealer retail asking prices.","buying_guide":"Inspect the front and rear elements under a strong torch for fungus, haze and cleaning marks, since wide-angle lenses on 645 are particularly unforgiving of internal contamination. Check the aperture blades for oil, confirm the diaphragm snaps cleanly across the full f\/2.8 to f\/22 range, and turn the focus ring through its full travel to feel for stiffness, dry helicoid grease or a sticky stop-down lever.
