The lens provides a reproduction ratio of 1:2. To reach a reproduction ratio of 1:1, it’s necessary to use an M2 extension ring. The lens may be used as a normal lens and focuses out to infinity. As the lenses focused on nearer subject, the aperture opens automatically. Because the front lens is so deeply set, a lens hood isn’t necessary. Engraved on the side are the reproduction ratios 1:1 through 1:1.5 up to 1:2. It also features a diamond ribbed focusing barrel.
