Overall the Tamron SP AF11-18mm F/4.5-5.6 Di-II LD Aspherical (IF) shows good performance. Sharpness is consistant across all apertures and focal lengths, flare is very well controlled and vignetting is very slight. There is visible chromatic aberration and barrel distortion, especially at the shorter focal lengths. However in extreme wideangle lenses of this type such aberrations are probably to be expected.

If you're looking for an ultra-wide zoom for your 1.5x or 1.6x lens factor DSLR then I can recommend the Tamron SP 11-18 f/4.5-5.6 Di II LD to you. The price is attractive and the lens is capable of producing high quality images. If you are the owner of a Canon D30, D60 or 10D, and therefore unable to use the Canon 10-22mm lens without performing warranty destroying surgery, the new Tamron provides an attraction option.

The Tamron AF 11-18mm f/4.5-5.6 Di II SP is surely capable to deliver decent quality images but the truth is that the competition is generally better in most aspects. Regarding the comparatively slow speed (max. aperture), the subjectively lower build quality as well as the rather limited zoom range it is also a bit strange that Tamron is asking a higher price point compared to the Sigma and Tokina counterparts (locally at least).
