Compact, lightweight, nice rubber lens shade, sharp, great color reproduction on Provia 100F. Very affordable, and there are many of them on the used market...

None. There is an ever-so-slight image quality fall off wide open (This could just be my imagination), but at all other aperatures its razor! I almost never shoot it wide open but would not hessitate to do so. Wish Mamiya had half-f/stop clicks on their lenses but not a big deal at all.r

This is a fine lens in one of the best wide angle perspectives; 35mm focal length equivalent in 35mm SLR systems. Mamiya did it right on this lens. It is a great people lens as well as a manditory wide angle for nature and scenics.e

Small, fast, sharp; uses 58mm filters. One of Mamiya's sharpest 645 lenses, easily their sharpest W.A.

55/2.8N has cheaper build quality and compressed focusing scale when compared to 55/2.8S

An incredibly sharp, compact lens at a very good price. Hands down, one of Mamiya's best 645 lenses.

55/2.8 compares well to Hassy 50/4

Very sharp

Mechanical problem with auto diaphragm (sticks) - returned to Mamiya for repair

Light and sharp with a good maximum aperture. However, the DoF markings are wildly optimistic and by my calculations out by a couple of stops. If you want sharpness and you use the DoF markings, pretend that f11 is f5.6 etc.

Good
