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: 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: 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: 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 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.
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.
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...
