Reviews
Ken Rockwell’s Tokina 11-16mm review — Ken seems to really like this lens, and declares it to be superior to Nikon’s own 12-24mm lens, and falls just slightly short of the much more expensive (and full-frame) Nikon 14-24mm lens.
Interesting is the fact that the Tokina 11-16mm becomes usable on the Nikon D3 at 15mm focal length — Ken has samples in the review.
VadimOm says that the Tokina 11-16mm can be used on full-frame, FX digital SLR cameras from Nikon is you zoom the lens to 16mm. There will not be any vignetting at that focal length, and only slight vignetting at 15mm.
Photozone.de, in this Tokina 11-16mm review, declared the Tokina AF 11-16mm f/2.8 AT-X Pro DX lens as ” … currently the best ultra-wide angle zoom lens for Canon EOS APS-C DSLRs. The resolution is impressively high throughout the zoom range (albeit a short one) and across the image field”.
Compared with the Canon EF-S 17-55mm — Blake Cook wrote a comment in this forum post that the Tokina 11-16mm beats his EF-S 17-55 IS in terms of sharpness at f/2.8 (that’s the lenses at wide-open aperture), color and contrast.
Sample Photos
“msp-photo” shot some lovely landscape and abandoned warehouse photos with the Tokina 11-16mm mounted on a Nikon D7000. Read how the images were post-processed.
DanielKHC’s HDR Set on Flickr — Most of Daniel’s photos in this set were shot with the Tokina 11-16 mounted on a Nikon D300.
The D300’s ability to shoot bracketed exposures at up to 9 bracketed shots at 8 fps in 1/3, 2/3 or 1 EV increments helps increase the success rate of the HDR sequence.
From the photo notes, Daniel uses Photomatix and Adobe Photoshop for producing the final HDR image.
Some of my favorites from the set are JBR: Jumeirah Beach Residence Gold, Afternoon Break, Cutting Edge Architecture, Made in Finland and Touareg.

I count 11 images, there might be more by the time you read the thread.
I like the closeup perspective shot at f/2.8 for this photo.

Two outstanding landscape images of shelf and mammatus clouds by Allan Jeffers, who mounted the Tokina 11-16 on a Canon 30D to shoot these photos.
Night landscapes — You’d have to first create a free login account, but I think it’s worth the effort as this forum post has five, fine night scenery photos shot with the Tokina 11-16mm and a Canon XT / 350D.
