Hey all, Just wondering which speedlight you all think is best for the D80? I assume that both the SB-600 and SB-800 are fully compatible with it, though I did see something about iTTL (no idea what this is...) and the D80 didn't come up as compatible but I'm not sure if it was up-to-date or not. The SB-800 is a bit more expensive than the SB-600, but would the 600 be adequate for live music photography? That is basically why I'm looking into speedlights.. Thanks to anyone who can be of help!
