Interesting. Sigma just announced an IS version of the 50-500 at PMA. This might be worth waiting for.
Sigma stabilizes 50-500mm ultra-telezoom: Digital Photography Review
F6.3 @ 500mm way too slow and i bet it is slow focus
That depends on your body. With my 7D, which performs well at higher ISO's, f/6.3 might not be so bad. Of course I'd love the Canon 500mm f/4, but that is way out of my budget and I'm going to wait and see before I forget about this one.
As for focus speed, a lot of birders use the old Bigma with good results. Songbirds are very fast moving small targets.
I've also seen some very nice surfing images taken with the non-IS Bigma (but this is a type of photography I know nothing about).
