I use it all of the time. Definitely a go to lens.

Summary: I bought this product because I needed a Telephoto lens. After a few months of debate I went with Sigma because, well, I like Sigma and I'm not a fan of the Canon 70-200 color. I like the all black finish. From all of my research, this lens comes second to the Nikon and Canon version. That being said, it doesn't slack on quality or durability.
Summary: Perfect answer to my problems catching the fast action of ice hockey. Auto focus is spot on most times and super silent motor. This is a sturdy product worth the money. After a while, you get used to the size and the weight of this monstrosity. When you get rave reviews for your fantastic shots, it makes it all worthwhile.
Summary: I shoot at a semi-pro level. This was a great lens to add to my bag. It did not break the bank like the Canon 70-200 2.8 IS. I have shot with both lenses side by side. I will say the Image Stabilization on the Canon is better just not 2x the price better. Also, I have noticed some slight chromatic aberration and soft edges with this lens. Nothing I cant fix in post, but its enough for me not to give picture quality a 5 star rating.
Summary: Several years back, the Pentax DA lenses seemed fine but with money being in short supply so I decided to wait. Bad move on my part! In the following years, prices on all new lenses kept going up until I now fine them costing much more. More than I feel inflation would justify. Ever since Pentax announced a possible full frame to be released sometime in 2014, the cost of any full frame lenses have sky rocketed also, even for the used market..
Summary: I have this len for a week now and I'm very pleased with the results. It is extremly sharp at f4 and AF is very very fast. This is my first Sigma so I had some concerns but it works perfectly on my 60D. Also, many reviews complained about the weight. It is not a feather but not a rock either. Very easy to move around with. OS is effectivly ~2 stops and you can clearly hear when it locks which helps me to understand when I can fully press the shutter. Awesome value.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Summary: OS makes a world of difference with handholding. The OS version of this lens appears sharper and seems to focus more quickly than their previous version. Not as heavy as some of the other lenses that I have used.Now I don't have to carry the tanks.
Summary: If you are like me and cant justify the price tag of the Canon L 70-200 then this is the lens for you. Compared to the kit lenses this is a far superior product and looks and feels great in the hand. The pictures are super sharp and its nearly silent at focusing. Well worth the money.
