This has been a LONG time coming! The D5 introduces quite eloquently the new Nikon SB-5000 and its wireless Creative Lighting System. You still have iTTL Flash Metering, but the camera and flashes talk wirelessly as well as optically. The HUGE advantage of wireless over optical is no more worrying about line of site for triggering your flashes. So for example if shooting along the Texas Coast with us in November and you need to use your SB-5000 with your long lens, no more cables between the camera and flash to fire and meter. No more wires to get caught in branches or scare off birds!
Besides having a wireless capable body (only the D5 & D500 so far), you need to have the SB-5000 and WR-R10. If you already have the WR-R10, it needs to have firmware 3.0 which Nikon is doing for free (that is not a typo). Once you have all the pieces, pairing the flash, remote, body, all together is simple. But the controls are different with the body doing much of what was done on the flash. All my pieces just arrived yesterday and while all working instantly, learning what to push when to get the desired effect is not ingrained. Once it is, I’ll post the settings (instruction book leaves out a couple of things) and how I’m incorporating this very new and exciting technology into my photography. And yes, I have updated my D5 settings with this new technology now in hand :-)
