Sample Images
Here're some sample images taken with the EOS 7D and RAW-converted via DPP (without auto-correction). As mentioned the tested sample had a bit of centering issue so you may be able to spot some fuzziness here and there.
Click on a thumbnail to view the original file (opens in a separate window). Please note that the originals are FULL SIZE samples
(=several megabytes) thus requiring a significant amount of bandwidth so please take care of the limited resources here.

VerdictThe Canon EF-S 15-85mm f/3.5-5.6 USM IS is certainly a desirable lens ... if you can get a good one (ours had a bit of QC issue). The resolution is generally very good from 15-50mm whereas you should expect some border softness at 85mm. A weak spot of the lens is the amount of vignetting which is extreme at 15mm @ f/3.5. An edge shading of 1.94EV represents a new (negative) record here at PZ - the lens is somewhat underdesigned here obviously. However, stopping down resolves most of the problem. The amount of distortions is typical for such a lens (heavy barrel distortions at 15mm). Lateral CAs can be visible at the extreme ends of the zoom range.
The build quality of the lens is very good and definitely an improvement over previous Canon consumer zoom lenses. Typical for Canon lenses featuring a ring-type USM the AF performance is very impressive. The IS ("Image Stabilizer") works just fine within its limits but that's a proven technology by now and no real news anymore.
Overall we'd say that the lens is slightly over-priced regarding its performance but eventually the street prices will come down to more sane levels.
