Sample Shots

Here're a couple of sample shots taken with the EOS 350D and RAW-converted via RSP 2006. Unfortunately the local weather was rather mixed at the time so I apologize for the mediocre quality.

Verdict

The Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] may have one of the funniest names around but the performance of the lens is serious at least regarding resolution where it was capable to deliver some of the best MTF50 figures to date. On the downside the very high field curvature at wide angle settings can be a problem in some situations (flat or very deep scenes at large aperture settings). Vignetting and distortions are about average for a lens in this class. CAs could be a little better at 17mm but otherwise the issue is quite well controlled. Mechanically the lens isn't top notch but it compares very well here to other third party lenses. Thanks to the very moderate price tag the lens is highly attractive and definitely worth a deeper look when shopping for a quality standard zoom lens for your APS-C DSLR.
