I have that Sigma, and quite like it. I have used it several times to capture fast
moving objects with the lens mounted to a monopod. (Powerboat racing).
It is very light and handles well, making it a better choice sometimes
than the A* 300mm + TC wich I also have.
It is true that the bokeh is sometimes disturbing, you can get strong
donut-shaped highlights depending on the lighting situation.
Sometime, when I have more time I will put some of those Powerboat shots
up on my WEB gallery ...
