As the second in the series of these lenses, the Rokkor-X lenses were redesigned slightly when the X-series bodies were produced. Rokkor-X lenses offer Minolta's exclusive Achromatic Coating as well as the utimate in computer design. This lens is constructed of 3 elements in 3 groups with an angle of view of 24 degrees. Designed with a short mount and no focusing ring for use with the Auto Bellows 1. The focusing range with this bellows is all the way from infinity to 1:1. This lens' relatively great focal lenght enables greater lens-to-subject distance, with resulting greater freedom in placement of lighting equipment. It's automatic diaphragm operation facilitates focusing and viewing up to and after the moment of exposure.
