This new "II" version is the same as the original Tokina 11-16mm lens, but with supposedly slightly better multicoating. More importantly, the "II" version adds an internal autofocus motor in the Nikon version so it now autofocuses even on Nikon's cheapest cameras.
It is built more solidly than Nikon or Canon's own lenses.
Instead of instant manual-focus override by grabbing the focus ring, you can switch quickly between auto and manual focus simply by pushing or pulling the focus ring.
Optically, it's fine, and a stop faster than anything else made in this format for use in low light.
