I've had the lens for 3 weeks and run a few tests. I've determined that the lens doesn't perform any better in low light then the Canon 18-135mm. In normal light the photos are sharper but the difference wasn't as significant as I expected when viewed at less then 100%.

Durable; Easily Interchangeable; Full Time Manual Focus; Nice Bokeh; Strong Construction

Poor in Low Light

Developed to fit the requirements of advanced amateurs, this new standard lens is an excellent all-round performer, featuring high-grade external finishings. Its 5.7x zoom range (24-135mm equivalent in 35mm format) covers wide angle to telephoto, and a host of high-end features that deliver great...

I bought this lens to replace the kit lens that came with my camera. It provides consistently sharp images. It focuses quietly and quickly. While it is somewhat heavy, it is well worth the trade off for the images it captures.

Consistent Output; Fast / accurate auto-focus; Strong Construction

Heavy

Ik heb dit objectief speciaal gekocht om op reis mee te nemen. Het bereik is perfect voor de vakantiefoto's. Het objectief is universeel te gebruiken. Alhoewel niet echt licht van gewicht is de balans (ik gebruik ze op een 20D of 30D) zeer goed en het geheel is nog net draagbaar.

Solid lens at a great price, easy to use with good results.

The Canon EF-S 15-85mm f/3.5-5.6 IS USM is a general-purpose lens designed for Canon's range of cropped-frame DSLRs, which means all bodies apart from those belonging to the 5D or 1D series.

Flexible range including 24mm coverage; Sharp details into the corners; Quick and quiet USM AF with non-rotating barrel; Smooth manual focusing ring and distance window

Poor vignetting with visible darkening in corners; Modest image stabilisation in our tests; Some creep between 24 and 50mm (actual); As usual for a non-L lens; no hood supplied

The EF-S 15-85mm f/3.5-5.6 IS USM zoom lens is one of two lenses announced by Canon in September when details of the EOS 7D were revealed. It's offered with the 7D body in the Platinum kit and covers a wide-to-telephoto zoom range of roughly 5.6 times.

I purchased this lens for a trip to Yellowstone and it performed great! I got it refurbished from Canon. The zoom range is ideal for walk around.

Very Sharp; Good color and contrast; IS works great and AF is spot on

Wish it was 77mm instead of 72, so more of my filters would fit it; Price still a little high

With Image Stablisation, UD elements and an Ultrasonic Motor, is this feature-filled objective the perfect kit-lens replacement?

Excellent handling and IS system

Drop-off in MTF curves

The Canon EF-s 15-85mm is an excellent lens for any photographer. In the 1990s my wife and I took a trip to Europe and I took my trusty Canon A1 with the FD 28-85mm f4 lens along with a few filters and some 20 rolls of film.
