Yes, I would recommend this to a friend

Consistent Output; Durable; Fast / accurate auto-focus; Lightweight; Nice Bokeh; Strong Construction

Piqué superlatif pour ce sigma et surtout dès la pleine ouverture; le centre est exceptionnel, les angles très bons (il faut visionner à 100% pour distinguer la différence entre les angles et le centre). Avec un Canon 60D, les clichés à 2.8 en basse lumière sont étonnants de précision.

Piqué à toutes les focales et dès 2.8; Qualité de construction; Livré complet avec pare soleil et housse; Compacité et poids

This Sigma lens, which can only be used on DX bodies, is a very versatile lens with few drawbacks.

The best sub-$700 stabilized f/2.8 midrange zoom

No full time manual focus

I bought my Canon EOS 7D as a body-only, eschewing the standard kit lens for my own collection of glass. For a long time, the lens that was almost permanently glued to the camera was a 35mm f/2 prime, with a 28-300mm as a typical walkabout alternative.

The lens is Awesome, it was delivered on time. The service was great. Its always good to talk to someone on the phone, discuss the product and then buy it.

For those who are looking for a pro lens at wide angle zone, this lens fits the bill perfectly. I have a T1i and was looking fr a good upgrade from my kit lens. The other options are Canon 17-55 and Tamron 17-50.

Great standard zoom! Didn't know what I was missing. Smaller than Canon's offering and much more affordable. Autofocus at first seemed iffy but was using in inadequate light. Turns out to be most accurate 3rd party lens I have.

Consistent Output; Fast / accurate auto-focus; Nice Bokeh

This is a great lens for the price. The focus ring is very sensitive, but that is the only downside.

This lens worked wonderfully for a wedding I recently photographed. Great pictures from this lens and my Canon 60D. About half the price of the Canon lens.

Fast focusing; Very sharp

heavy and bulky

I really like this glass, its big and beautiful! really smooth hsm motor. Really smooth zoom ring, very solid construction! Lens hood stays intact really good, clicks in nicely! I would recomend this to anyone who has a d7100 or lower in the dx range.
