請問有無師兄用緊 Sigma 10-20mm F4-5.6 或者 Canon EF-S 10-22mm f/3.5-4.5 USM，小弟有興趣呢個range，但我知前者同後者價錢相差$1000~$1200左右，但質素差別不太多，希望C Hing們幫幫忙........感激！

但質素差別不太多!!!!!!!!

Ching, as you asked this:

I assume you are using a canon body.

in that case, it is obvious that the Canon EF-S 10-22mm f/3.5-4.5 USM is just superior. there's almost no need to compare (or where have you been comparing, 質素差別不太多 is impossible.

a few years back, there werent much alternative to the EF-S 10-22mm, the sigma was the only other choice and the pricing was (still is) attractive.
but the Canon one is the one to get.
