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 bought this for night sky photography but I've also been using it for landscape shots. This is my first wide angle lens and I was worried about getting this one over some other lenses I was looking at but I'm soooo glad I picked this one up.

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

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.

It is noted for its good processability. I bought it to take pictures from landscapes and northern lights and i don't regret it. The Lens works fine, and has a fabulous focal length. The autofocus is not as fast as other lenses like the SONY SAL1650 2.8 SSM but in most cases it doesn't matter.

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.

Great lens, I use it mostly for astrophotography and landscape. Good price for a versatile and sharp lens.

I use this lens for shooting the Milky Way, landscapes, and to give a slightly different perspective. To say I am in love with this lens is an understatement. However, shooting with an ultra wide angle lens is different and takes a little learning.

Consistent Output; Durable; Fast / accurate auto-focus; Rugged; Strong Construction

The Tokina 11-16mm for Canon, Nikon and Sony APS-C bodies is quite heavy for a telephoto in this range, and also on the expensive side. It has a constant maximum aperture throughout its entire zoom range, so users can shoot at f/2.8 even at 16mm, allowing for fast shutter speeds in low light and a...

I am satisfied by this lens. It creates great wide shots to be able to capture the whole room. The best part is it does not get odd light glares like my Sigma 18-250 mm lens. It is good lens for close ups, wide shots, shooting the stars at night, and landscapes.
