The built in helicoid extension allows focusing from infinity to ½ life size magnification.

With extension tubes or the Auto Bellows, magnifications to 3X life size are possible. This great lens is offered at just £199.95, a very fair price when you consider Mamiya were asking £720 for one, and you will probably 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.
