I was using a Tamron 18-270 lens as a walk around lens but was not satisfied with quality of the pictures. Sold the Tamron lens and got this one and have been using it for 4 months. As other canon lenses, it captures very sharp pictures and colors are very accurate. Focus is quick due to USM.

Having a much higher optical quality than its predecessor (17-55mm) the Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens is an excellent all purpose lens that will be perfect for the APS-C (crop) sensor camera.range. Ideal for landscapes, street photography, portraits etc.

I have had this lens for one and a half years, and it has been a nice mate for my camera. It is great: very sharp from 15 to 85 mm (although not so much in the corners at its widest aperture), very good at f11 for landscape photography.

Sharp; quick focus; good range

Non constant aperture: f5.6 is a bit slow

easy to use,extremely sharp,quick silent focusing,no chromatic aberration

no lens hood!!

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.

At a casual glance Canon's 15-85mm lens looks inferior to Nikon's 16-85mm in one important aspect: it has only a single-mode image stabilisation system against the Nikkor's dual-mode system.

Excellent handling and IS system

Drop-off in MTF curves

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

EF-S lenses get a bad rap in my opinion. Because they are specifically designed for the APS-C format they can be made smaller and lighter and that makes them a lot cheaper. The does not mean that they are optically inferior, as born out by the 15-85mm.

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 very good, if not excellent results for sharpness, resistance to chromatic aberration, distortion and corner shading, Canon has released an excellent general purpose lens.
