I've got another practice, "test" shoot on Sun with the twin of the girl from last week. This time I'll be using my other D2X body. It's the original one, the very early unit that's already been sent back to Nikon for focus problems. Seems to be much better than before now. Haven't used it on a ppl shoot yet, only for birding. I do not want to get the crap results I got last wk. Any tips to help ensure I get crisp, sharp images this time?
