I currently have an XSi and have been doing a lot of indoor portrait shooting. (I do very little to no sport shooting.) I find I have to use my Tammy 17-50 a lot because of the limited space I am shooting in, sometimes space is a problem. My question is:
Would it be better to purchase a wide angle lens such as Tokina 11-16 or Canon 10-22 or go ahead and upgrade to a FF and have the higher ISO capability?
I would appreciate any and all input.
