Tokina has announced an updated version of its highly-regarded 11-16mm F2.8 wideangle zoom for APS-C SLRs. 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. US distributor THK Photo tells us the Nikon version should be available around April with a Canon version following around August.

Unlike version 1 of the lens, there is no mention of a Sony version.
