My favorite photo store told me the 550EX would be best for my 10D. I'm going to be shooting a wedding reception in a gym setting with high ceilings and florescent lighting. I will be shooting some available light B&W with higher ISO's, but also want to use lower ISO's and a flash. I've read negative things about TTL and wonder if for the price I would be better off with something else. The other options I'm considering are the Nikon SB800 or the Sigma 500DG Super. I read at http://shootsmarter.com/infocenter/wc031.htm
that the Nikon flash on a 10D was much better than the 550EX, but I'm a bit nervous about the compatibility and purchasing the Nikon flash based on one review.
I plan on getting the Lumiquest Pocket Bouncer, too. Is a flash bracket also going to be a must have? I "might" be doing more weddings, so I am willing to get the best I can afford now which would be in the $600 range or less.
