Excerpt: I was disappointed with the first photo I took with this lens. Also with each one after. They were all dark. I returned it as I felt it was defective. The staff was very helpful with this process.
Summary: OWNERS OF SONY A65 AND A77, PLEASE READ! The AF on this lens will NOT work with the a65 or a77 unless a firmware update is performed by Sigma. Also, if buying this lens either used or outside the manufacturer's warranty, Sigma will charge a fee of $50-75 plus shipping to and from, which will take...
Summary: Bought this lens as a replacement/upgrade for my Nikon 18-55 kit lens. Autofocus and speed are indeed better. The quality of the pictures are about the same. I guess I could sort of live with that. What I find unworkable though is the 'barrel creep' of this lens.
Summary: I bought this lens to take on vacations, and as a general walk around for my Canon T1i. I wanted to be able to take landscape shots, have a little reach on the tele end, and the macro was a bonus.
AF problem was a shame when it took such sharp images

Summary: Bought this lens from amazon warehouse and was excited when it arrived. However putting it on my Nikon D200 this excitement soon changed to annoyance as I quickly realised something wasn't right.
Summary: On a D5100: The autofocus is inaccurate (about 3 inches off each time) and fails in average indoor light. When manually focused at f/4, the results are sharp at the short end. I had the Sigma 150-500mm, and decided to order this (17-70mm) and the 70-300mm as Christmas presents.
Summary: I have already sent a review which you have seen fit not to publish, so I'll try again, more briefly. The Sigma 17-70 is simply not worth even half the price and is out performed in all respects by my cheap Canon 18-55 kit lens. Antony Brown.
Summary: I'm sure this is a great lens, but the auto-focus system does not get on well with a Canon EOS 40D - specifically the lens spends a lot of time "hunting" for focus. I upgraded from the original non-OS non-HSM version of the lens, but now I've gone back to that lens.
Summary: I bought the lens in order to replace the canon 17-85 IS. I use for a very short period, because I experienced a front-focus problem. I sent to an authorized service and the calibrated on my canon 40D.
