Manual focus design offers a 2.3' minimum focusing distance along with a 1:4 maximum magnification ratio to suit working with close-up subjects.

Rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality when working with selective focus techniques.

Built-in retractable lens hood helps to block stray light from reaching the lens, preventing flare and ghosting.
