I like my 8-16 Sigma, enough to be the only lens I've travelled with on all my overseas adventures. It's a funny thing to use, really steep learning curve and getting a solid exposure is often difficult. One interesting note is don't worry about it being a 4.5-5.6, the lens tends to let in a pile of light and I find I'm always reducing the exposure by a 2/3's to a full stop compare to 'normal' lens.
Also the lens is rather small and light.
