Hi all,
I've just got myself a new Sigma 8-16mm from HK for $720.
Very impressed with it so far, the focussing is very fast thanks to the HSM, the only thing I can fault it on is that it slightly under exposes, but I shoot in RAW, so no issues really.
Solidly built, and contrary to some of the reviews I've read, it does come with a slip over threaded mount for filters & the lens cap.
I'm constantly adding to this set if you want to see some shots:
