I am looking for a wide angle lens to buy as what I currently have doesn't do the job. I was looking at the Canon EF-S 10-22mm f/3.5-4.5 USM. Looks good, but the price is high and it made me look at the Sigma 10-20mm f/4-5.6 EX DC HSM. The price is lower, but from what I read it does really well.
What are your thoughts about these lens? Have you used any of them? Any other suggestions? I'd like to try and keep the price below $500.01
Thanks for any help, --Calfo--
