A well built lens by Sigma. Those who are not used to (inexperienced) in focusing properly will realize that this lens is very sensitive. Two objects sitting next to each other but one is slightly farther away from the camera (say 1-2") will show noticeable difference in the sharpness level. So be very careful with pointing at the right object. Otherwise practice will bring you closer and closer to great results. Very light for its size and capability compared to the Nikkor 70-300mm or 18-200mm VR or not. Well-priced ($600-$700). Fast built-in motor (HSM) and very very quiet. The best part is the f/2.8. Able to capture images in low light settings, indoor, fast movements, way faster and way sharper than 70-300mm or 18-200mm (f/3.5 or f/5). Highly recommended.

I really wanted this lens to be good because it looks pretty great on paper. Unfortunately when it arrived the autofocus didn't really work at all. I ended up sending it back to Amazon.

When I received this lens I took several test shots at F/2.8 on up to f/16 to test for sharpness (tripod mounted) at a distance of 5-6 feet. My lens was suprisingly soft at f/2.8 to f/5.6 or so, even compared to other telephoto lenses (e.g., Nikon 70-300mm)at comparable apertures. I called Sigma technical support but they were not much help so I sent it back. I was really hoping I would like this lens since it is much lighter than my (full frame) 70-200 f/2.8. I received a full refund from Amazon so at least the experience did not cost me any $$.
