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 3-6 weeks. Please research if the firmware update has been done before buying 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. I've never purchased a non Canon lens before, but heard good things about the previous version of this lens. First thing I noticed, the lens does not fit onto the camera with the ease that a Canon lens does. It goes on, but required significant more torque, and this worried me.
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. The AF would continually search even when it was pointing at a still object, it was even worse under artificial light indoors. I tried the lens on my spare D50 and the problem still persited. I have since sent the lens back and won't be ordering a new one.
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. Maybe the HSM is just too fast for the older EOS models!
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. While the 150-500 is a great lens, the build quality and image quality on the latter two is disappointing.
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 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. For the time I used the lens I found the lens very sharp and well build, on both matter much better than canon 17-85. Focus was on par with canon 17-85. I found a little inconvenient the wide focus ring; while auto focusing my fingers keep blocking all the time the ring.
Summary: Bei diesem Objektiv bilden sich bei Gegenlicht am Tag, aber besonders bei Dunkelheit auch bei großem Abstand zu Lichtquellen riesige grüne Flecken! Da ich gerne nachts fotografiere, ist dieses Objektiv leider für mich ungeeignet und für meine Zwecke überhaupt nicht zu gebrauchen. Gerade bei der Nachtfotografie bilden sich zig grüne Punkte an unverständlichen Positionen im Bild ab.
Excerpt: Это мой первый отдельно купленый объектив, хотя видео профессионально занимаюсь 20 лет (Sony HVR z7) Потратив неделю, заказав в двух магазинах и попробовав 4 объектива сделав тесты и проконсультировавшись с опытными спецами обнаружил (к своему огорчению) что сей девайс откровенно хуже по резкости штатного 2-х рублёвого KIT 18-55 mm IS II.
