I used to be a Canon shooter but made the switch to Nikon after much soul searching and web reviews. Don't get me wrong, the Canon 50d was an awesome camera but, one thing really bothered me. I do a lot of remote flash shooting and Canon was not able to a Second Curtain flash remotely. This caused a lot of problems when doing night shoots. I really don't want the main subject in sharp focus and have their trail lead them. The trail should be behind then subject in sharp focus. Anyways, I'm loving the Nikon D90 a whole lot. Has yet to let me down or make me regret my decision.
