Before i posted this I did run a search on the forum but didn't find anything hence i am posting this.

I would like a wide angle lens that i can use for landscapes but i would like to take photos of group of people indoors at parties.

Canon EF-S 10-22mm f3.5-4.5 USM Lens

Sigma 8-16mm F4.5-5.6 DC HSM Len

I have a 50mm f1.8 and a 18-200mm lens already.

Thanks
