This is the Tokina 11-16mm f/2.8 AT-X 116 PRO DX II lens:
The new Tokina 11-16mm II features a built-in “Silent Drive-Module” (SD-M) focus motor that allows it to focus on all Nikon DSLR cameras (including the newer digital SLR models which do not come with a screw-drive autofocus motor) and replaces the Tokina 11-16mm f/2.8 AT-X PRO DX.
Accessories and add-ons
The filter thread size on the AT-X 116 PRO DX II is 77mm, which means you’ll want to be looking at purchasing 77mm filters.
