This is an excellent / excellent + condition Mamiya 645 80mm f4.0 N Macro lens, including both caps.
This lens in is excellent mechanical and optical condition. This lens has only very minor signs of use except for some obvious marking on the mount that has zero effect on use; I guess it has had a knock at some stage but it has been repaired and fits perfectly on the camera. It has superb glass with just one tiny hair and a few very small dust specks; no other issues.
This Mamiya 80mm f4 Macro features outstanding resolution, and flat field correction required for copying flat artwork with edge to edge sharpness. The built in helicoid extension allows focusing from infinity to ? life size magnification. Applications include copywork, macro and close up photography of all objects from product photography to flowers. Fashion and beauty photographers find the 80mm f4 Macro particularly useful for a variety of subject close ups and normal shots. An extremely versatile lens, the 80mm f4 macro can also operate as an excellent normal focal length lens focusing to infinity for portraits, landscapes and general purpose photography. With extension tubes or the Auto Bellows, magnifications to 3X life size are possible.
This great lens is offered at just ?169.95, a very fair price when you consider Mamiya were asking ?720 for one, and you will certainly have to pay more than this for a standard 80mm f2.8. This lens is about the same angle of view as a 50mm standard lens on 35mm cameras.
