a high performance ultra wideangle zoom lens designed exclusively for digital SLR cameras using APS-C size image sensors.
The lens provides reliable performance in a compact size to meet the needs of digital SLR camera users pursuing creativity in wideangle photography. The lens uses a new optical system specially designed for digital SLR cameras, in addition to the use of a glass-molded aspherical element having a large clear aperture, hybrid aspherical elements, and elements using such special glass materials as high index/high dispersion glass and low dispersion optical glass, for outstanding optical performance.
* "Di (Digitally Integrated design)-II" is the designation Tamron puts on lenses designed for exclusive use with digital (APS-C size) SLR cameras, featuring optical systems optimized to meet the performance characteristics of digital cameras.
* "Di-II" lenses cannot be used with digital SLR cameras using image sensors that are larger than that of an APS-C size imager, or with 35mm film SLR cameras.

I've never had particularly good luck with Tamron, but the reviews for this lens were good and I gave it a try... Pleasantly surprised! It is very slow to focus but I'm mostly using for real estate and that isn't a concern to me. It's an excellent alternative to the Tokina 12-24 with a better price point.
I really really like this lens. It does everything you can ask of a wide angle lens, and it does it with sharp focus and consistently good clarity. I had been told that Tamrons sometimes had focus problems. Not this lens. I have some shots in my flickr photostream that show how really terrific this lens is. I would firmly recommend it.
