Greetings fellow Nikonians. I just purchased a used D700 and usually shoot with a D90. I'm guessing there will be a learning curve. I'm anticipating that it will arrive a day or two before our football championship game on Friday and I'd really like to use it for that game. I love my D90, don't get me wrong, but when I purchased it, I was just playing. Now I am selling my photos and want to do the best I can. Any suggestions or quick tips will be greatly appreciated.
