Lens Build is on the Very Good Side

Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens The Canon EF-S 15-85mm is for sure a desired lens ... Providing you can obtain a good one (mine had somewhat of a QC problem). In general the resolution is excellent from 15mm through 50mm while you should plan on seeing a little softness of the borders at the 85mm long end. A sore spot of this lens is the tremendous quantity of vignetting at 15mm @ f/3.5.

The slight shading of edges of 1.94EV epitomizes a new negative mark- the lens is obviously somewhat poorly designed in this area . However, stopping down some takes care of most of the issues. The large amount of distortion is usual for this type of lens (with heavy barrel distortion at 15mm). Also, lateral CAs become visible at both extreme endings of the zoom spread.

If you need a low light lens, this isn't it. If your primary objective is to take pictures in low light situation such as weddings and concerts, then get the 24-70mm IS f/2.8L USM instead.

The lens build quality is on the very good side and definitely an edge up over the previous consumer Canon zoom lens. Predictable for Canon lenses is a ring-style USM while the AF operation is most remarkable. The Canon IS ("Image Stabilizer") functions very well within its limitations but that's already a given technology today and nothing new any longer. Overall I'd say the lens is a bit over-priced in relation its performance but the street and internet prices will eventually drop to more realistic levels.  Feb 15, 2011
