I'd like to know what is the best lens for shooting portraits? I have the kit lens (18-55) that came with my Rebel XTI. Would it be good to just go with 18-55 or should I look at something else? When I return to the states I'll be purchasing 2 studio lights and a backdrop. The main reason I want to shoot portraits is my wife is thinking about modeling for a online lingerie shop.
if you would please help
