Summary: 1. I love it's solid structure with black color that goes well with my Canon camera body, (I do not like the White color of Canon 70-200 f2.8 or f4l, i think if i use these Canon lens on my 60d its looks like i am going to wear a white pants with a black shirts, looks so weird for me:)) 2.For an amateur like me, i am happy with the quality of pictures by this lens, day and night. 3. OS helps me alots coz of my shaking hands. 4.
Summary: So I used to own the Canon 70-200 2.8 II, and it took amazingly sharp images... and was an all around GREAT lens. I sold it to get the 5D Mark iii, and have never regretted that. But I needed the reach of a 200 and thought that I could compromise with this lens. Going in, I never expected it to be equal to the Canon, (as it was less than half the price). I have been impressed that the shots I took were pretty good.
Summary: in my professional opinion...the Sigma 70-200mm f2.8 APO EX DG HSM OS FLD telephoto lens is a fantastic performing lens...It's very sharp on both my 5D Mark III & 7D...bokeh is creamy & very pleasing...the focusing seems to be as quick if not a little faster than the Canon version 1 lens..
Summary: Really like this lens. I purchased to use for photos of semi-pro football games, many at night, and performance has been just what I hoped for. Quick focusing, even on poorly lit fields, super fast focusing during the daytime, and works well with my Sigma 1.4TC.
Summary: This lens focuses fairly quickly and quietly. Photos are crisp and clear. Macro quality is pretty good. No problems using it with Nikon D3100. The only drawbacks are: 1) this is a gray market lens (no serial number) - Sigma will not honor the warranty that comes with this lens. 2) the lens is pretty heavy. However, considering the price and quality, I can't complain.
Summary: I have been a professional photographer since 1996 using exclusively Nikon hardware. I bought this Sigma because we had a large event and I didn't want to spend another $1900 on a 6th Nikkor 80-200mm F2.8. SO I tried the Sigma. The images are excellent and damn near equal to the Nikon's images if you know what you are doing. The Sigma tends to run a bit hot and you must exposure compensate usually 2/3s to a full stop.
