Review on Sigma 17-50mm f/2.8 EX DC OS HSM FLD Lens: Large Aperture Standard Zoom for Canon DSLR - International Version (No Warranty) by Micha Pirecki ᠌

The fact that this lens has acomuple of FLD elements does not reallycommpensate for barrel distortion - i.

De tested a cheaper Chinese, the results were appropriate. The realcommparison "on the battlefield" clearly outweighs in favor of the Japanese B005, since the presence of aspherical lenses outweighs the benefits of HSM, which practically does not affect anything at such focal lengths and at a small angle of rotation. The B005 has bettercomlor reproduction, no worse bokeh, and a slightly wider angle than even Canon's. Soaps, vignetting and distortion, as well as HA were not particularly noticed. Autofocus is very accurate, no dancing with tambourines. So, either Tamron B005 (Japan) or Canon.
