Hi all! I'm looking into getting a second camera to use while I'm shooting weddings - right now I have a Canon 30D a Tamron 17-50, Canon, 28-90, Canon 50 mm and Cannon 70-300 as well as a 580ex flash. My question really is if I get a second camera - I'll be using one camera with a wide angle lens and the other with the telephoto - should I get another 30 D or go a step down, say a Rebel XTI? Or should I just scrap the whole second camera idea and get a couple of other lens'? I still want a 90mm telephoto! Decisions, decisions - help! Thanks!
