This lens is equipped with the rear focus system that minimizes fluctuation of aberration caused by focusing. It provides optimum image quality throughout the entire zoom range.

The minimum focusing distance of 150cm (59.1”) throughout the entire zoom range and has a maximum magnification of 1:4.2 make it useful for close-up photography.
