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.

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.

Lens oracle, Gary Wolstenholme examines the new 15-85mm IS USM lens from Canon. Canons' 15-85mm lens costs around ￡639 and is the natural replacement for their popular EF-S 17-85mm IS USM lens which can be had for around ￡380, due in part to this new lens becoming available.

Useful zoom range; Excellent sharpness at most apertures and focal lengths; Image Stabiliser; Good build quality

Distortion; Vignetting at 15mm; Flare and ghosting performance (no lens hood supplied

The Canon EF-S 15-85mm f/3.5-5.6 IS USM Lens delivers top-tier image quality over an excellent general purpose focal length range in a nicely-sized/weighted/built body with great AF and an excellent implementation of Image Stabilization at a for-what-you-get great price . I'm impressed.

Introduced last year, this extrawide zoom built for Canons with APS-C-sized sensors makes an attractive utility lens for the new EOS 60D or can serve as a wider, longer alternative to the Rebel kit lens.

A dream as a walk-around lens. The difference between 15mm and 18mm is very noticable and opens a whole new world of possibilities. The only real downside for me is the lack of weather sealing, because this lens will often be used for landscapes or seascapes in rather unwelcoming conditions.

1) unparalleled focal length 2) extremely effective image stabilisation 3) excellent center sharpness throughout; very good corner sharpness wide open; excellent overall stopped down to f/5.6.

1) Not weather sealed 2) Zoom creep beginning from about 40mm onwards

Sept 1st. Canon has officially announced the much rumoured Canon EF-S 15-85mm f/3.5-5.6 IS USM zoom lens. The Canon EF-S 15-85mm IS USM is designed to offer high end image quality, while providing focal length range coverage from approximately 24-136mm 35 mm equivalent terms.

I picked up this lens as a walk-around lens for my Canon 7D. As such it has fit the bill very nicely. IQ has been very good for my use as a walk-around lens. Construction isn't up to L glass but for the money its more than acceptable.

a little heavier than I thought it would be

The Canon EF-S 15-85/3.5-5.6 IS USM , ( buy from Amazon ) was introduced in 2009 as a replacement for the Canon EF-S 17-85mm f/4-5.6 IS USM , ( buy from Amazon ). In addition to the extra 2mm of focal length on the wide angle end of the range the lens was optically redesigned, adding 2 more aspheric...

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.
