#3. "RE: D700 built in flash as a commander" In response to Reply # 0
It might work for your project. The D700 as commander will control two groups wirelessly plus the built-in, plus an infinite number of flash activated slaves. If you use a flash cord, like an SC-29, SC-27 or even an older SC-17 on the hotshoe, you can contol one via cord, two groups via wireless controller, and an infinite number of flash-activated slaves.
