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: 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.
Excellent Build, Excellent Image Quality, great alternative to Canon.

Summary: I am a professional wedding photographer, and my Canon 70-200 2.8L IS had pretty much run its course, and I was no longer happy with the image quality. I didn't want to spend over $2000 on a replacement, as I am primarily a prime lens shooter and my 135mm produces images just as sharp as the new Canon 70-200.
Summary: I wanted a fast zoom lens for taking outdoor pictures of wildlife and my grandkids.The build quality is great. The lens Is a bit heavy. It take awesome low light pictures .My wifes says my pictures look like a pro took them now. I still have a lot to lean. But It makes it easier with good glass.
Summary: This is the latest generation of Sigma's popular 70-200mm 2.8. The new version boasts OS (optical stabilization) which is the first lens in this zoom range to offer it outside of Nikon. The clarity of the images are fantastic with excellent sharpness and color even in the corners. The bokeh is outstanding. The only lens better is the Nikon 70-200 2.8 v2 which is double the cost for 5% faster focusing. Hmmm...I'll go with the Sigma.
