Mamiya 645 m645 Super / Pro / TL 80mm f1.9 C Fast Lens -Bargain, Haze-
This is the very desirable late model 80mm f1.9 lens for ALL of the manual focus Mamiya 645/m645 cameras. It is, to my knowledge, the fastest lens for any medium format SLR system, just edging out the Contax 80mm f2.0.
The lens is extremely sharp with great color and is more than one full stop faster than the standard 80mm 2.8. The extra speed is a big help for low-light shooting and shallow depth of field and makes the image pop into focus better, allowing for easier focusing.
This is simply put the best normal lens that you can get for your 645.
This lens looks good but there is a slight haze on an inner element that may soften your images slightly. Otherwise the glass is clean and scratch free with no fungus or other problems. The focus and aperture are smooth. Caps are included.
