According to the D700 owners manual (page 189) "FP" will be displayed in the Flash Control Mode area of the shooting information display when the flash sync speed is set to Auto FP and an appropriate speedlight is attached.
I have a SB-910 attached to my D700 and have set the flash sync speed to Auto FP but I don't see the "FP" displayed in the shooting information display. I do see "FP" on the SB-910 display when I have set flash sync speed to Auto FP.
The SB-910 is turned on but not set to remote or master.
Can you explain why I'm not seeing FP in the shooting information display?
I can't get the "FP" to show in the Shooting Information Display on my D700. It doesn't show on my D800 either. I spent over an hour trying to get it to display but no luck. I think it's an error in the manual. Could they have meant it would display on the flash info screen? But Auto FP sync does work very well. I shot photos with shutter speeds from 1/400 to 1/2000 and got perfectly exposed photos.
I tried a little indoors experiment with my D700 and D7100 with an SB800. I chose shutter priority, auto ISO and set a shutter speed of 1/500. This gave an aperture of F3.5. In the shooting info display I see TTL over FP. The flash mode was TTL BL FP. I changed this to TTL FP and still I got TTL over FP in the shooting info display.
I then changed the shutter speed to 1/200. The shooting info display no longer showed FP, just TTL. I think therefore that FP will only be shown when the shutter speed goes above 1/250 or 1/320

With the same settings you used I don't get a "FP". What I get is: Optional, TTL, 0.0 over the flash lightning bolt.
What firmware versions do you have? I have A: 1.03 and B: 1.02. It might be older firmware but my manual is much older than that.
I tried different shooting modes (S, A, M) and the determining factor seems to be whether the shutter speed was above the auto-FP speed, either 1/250 or 1/320. My SB-910 always shows "FP" if I have auto-FP high speed turned on, regardless of the shutter speed.
Not sure why nothing else I've read (Nikon manual and at least 3 different D700 books) mentions that qualification.
I just upgraded my firmware. And just shot a few flash photos in different modes at 1/400 and above. My SB800 displays FP but the D700 info still will not show FP. This is pretty strange. I'll try another flash.
I think you've got it too, lol. The clue was in "Mastering The Nikon D700" by Darrell Young and James Johnson. It states: "You can safely leave your camera set to 1/320s Auto FP or 1/250s Auto FP all the time, since the high-speed sync mode does not kick in until you crank the shutter speed above the maximum setting (1/250 or 1/320). Below those shutter speeds, the flash works in normal mode and does not waste any power by pulsing the output."
I apologise for this breach of copyright, but I hope I have promoted the book rather than plagiarise it.
Dave, I figured it out. I was looking at the image data screen instead of using the Info button. I've had my D700 for 5 years now and it's the first time I pressed the Info button. It shows FP beneath TTL.
