This a super wide angle lens has received some great reviews. It has great optics and a wide f/2.8 aperture. It uses Tokina's One-touch Focus Clutch Mechanism to switch between manual focus and autofocus by snapping the focus ring forward for AF and rearward for MF. It's different, and it works well. This version of the lens has the Canon mount. Caution: This is a DX lens so it's not designed for full frame cameras (but it will mount on a full frame camera).
