The newest wide-angle zoom from Tokina is built for full-frame bodies. We got to check it out briefly in both Canon and Nikon mounts and it certainly feels like a solid lens, even a little heavy. The zoom ring is smooth, but takes more effort to turn than some of its competitors. The focus ring snaps nicely back and forth to switch from manual focus to AF, but it doesn't turn as far as some others, making fine focus control a little trickier. But, with a street price below $800, we're eager to see how it fairs from an image quality perspective.
