youre gonna love the 300. i came from a 20D + 10-22 + 24-70 + 70-200/4 + 85/1.8 kit.
i gotta say, i am MUCH happier with my current kit. IQ has jumped, despite the fact i've gone from "pro" glass to "consumer" ones. the xxD line has got nothing remotely close to the D300's af system. this alone was worth the switch. but the ergonomics and CLS?? its not just icing on the cake...its a whole other cake!!
the moment you take your first wireless flash exposure with the built-in flash commander, you'll never look back...
