Pentax medium format 120mm macro lens for the 645  system. Precision Japanese manufacture gives super smooth manual focus operation.  Equivilent to a 75mm in 35mm format this  lens is highly rated by reviewers. Quite bulky for everyday use, but partners very well with the 645N body. Excellent close up detail from this lens and has application for portraiture. A bargain at this price point. Comes with both lens caps.
