Tokina AT-X 116 Pro DX AF 11-16mm f2.8 II Lenses

The AT-X 116 PRO DX II adds a Silent Drive-Module (SD-M) focus motor that enables it to autofocus on all Nikon SLRs. The latest version also includes improved surface coatings (which are particularly important for wide-angle lenses) and adds a GMR sensor to locate the focus element s current position to speed up autofocus - a technology first introduced on the AT-X 16-28 F2.8 PRO FX full-frame wide-angle.
