Comments about Sigma figma 50-200mm f/4-5.6 DC OS HSM Compact Telephoto Zoom Lens for Nikon Autofocus Digital SLR Cameras:
A gift to someone close to me - so I can use it myself :) This lens is much better built than comparable Nikon lens. Metal ring instead of Nikon's composite material. Of course it does not provide the sharpness of a $1000+ lens, but I was surprised about it for this price. OS works! It bring in average 3 stops.

Comments about Sigma figma 50-200mm f/4-5.6 DC OS HSM Compact Telephoto Zoom Lens for Nikon Autofocus Digital SLR Cameras:
I bought this lens to use on D5000, mainly for sports photography. It works there pretty well: auto-focus is reasonably fast and accurate. I can track quick moving subjects, and the OS is surprisingly efficient. I get usable, though slightly soft, pictures even at 200m. It's not a very fast lens at f/4-5.6, just average. You need light.
Some say bad things about Sigma build quality, but I'm very happy with the quality and handling, it feels solid, particularly if you consider the price. Manual focus ring is only fair, not great, but much better than with e.g. D5000 18-55 kit lens.
The picture sharpness isn't great, the main reason I hover between 3 and 4 stars. Distortion is not a problem, and I've even taken some portraits where the bokeh is very pleasing.
Bottom line: not a spectacular lens, but good value for the money if doing sports. For nature photography, too soft.
