Received and tested Sigma 70-200mm f2.8 OS HSM lens today. I love it.
The focus is fast, and the image quality is great (slightly soft at 200mm f2.8). The OS (optical stabilization) worked great! It’s many times better than my previous Sigma 70-200mm f2.8 (non-OS) lens, in term of built quality, focus speed and OS capability.
For almost half the price of the Nikon version, it’s highly recommended.
