The Tokina 11-16mm DXII is a superb lens with solid construction. It is extremely fast at F/2.8 and therefore works well in low light conditions. The photos are sharp and clear. Definitely a good buy.

Durable; Fast / accurate auto-focus; Strong Construction

Heavy

This lens is super wide and seems to take very sharp pictures. Limited range, but I highly recommend this lens.

Perhaps the best Aps-C ultra wide angle lens today for Canon mount. See in more detail at: http://oldshutterhand.com/equipment-reviews/tokina-11-16mm-review/

Excellent built quality; good contrast and sharpness

chromatic aberration; price

I was a little concerned about buying my first non-Canon lens. But I had less money than I was concerned about not having a fancy red-ring. This lens is awesome. Great picture quality, fast-focus and... more great picture quality.

Sharp as sword! Built like a tank! Ultra wide! Fast Aperture- F/2.8! Reasonable price! Made in Japan! What else you want?

I actually went by the Review that Mr. Devesh Uba had posted and since I was looking for a Wide Angle Lens, I decided to go with this based on some other reviews as well. I got it today and was very happy with the Lens. Not used it much but I am sure it will serve my purpose in times to come.
