The lens is from a copier and designed for 1:1. These are not cheap lenses and for their designed purpose are fine optics. Xerox had a very sophisticated optical design department some years ago and worked with fuji on many lenses. We heard someone used this lens in a large format camera. The lens is 3 and one quarter inches tall by 3 inches in diameter not counting the outside rings. It weighs in at 2 and one quarter pounds.
