This high definition lens has an infinitely variable focusing system uses a double helical thread for precise and smooth operation down to the minimum focused distance of 24.1cm, which provides a reproduction ratio of 1:2. To reach a reproduction ratio of 1:1, it’s necessary to use a M extension ring. The lens may be used as a normal lens and focuses out to infinity. It has a wide scallop focusing barrel as well as engravings for exposure adjustments and reproduction ratios. Because the front line is so deeply set, a lens hood isn’t necessary.
