The D700 manual is 444 pages and I am surely glad I had it. I found it to be a really good read after playing with the camera for a few weeks.
Forget about "Invaluable", without the manual, the SB-600 interface would be plainly impossible to comprehend. These press-button-combinations-for-a while, meaningless icons and acronyms interfaces are so cumbersome, idiotic, hard to remember and time waster. I can never remember which sequence does what. Nikon completely missed on the ergonomic of that one. I don’t see why we couldn’t forget the flash UI altogether and just use the camera to program the flash directly. Is the SB-700 any better?
My friend bought a Sigma flash for his D7000 and that thing is even worse. With the manual, it took the both of us hours to figure out how to remotely fire it with the D7000 in commanding mode and even then, we were not quite sure what it was doing, sometime over/under exposing apparently at random. For the longest time, the flash was firing but did not appear in the photo and after a while at being zapped at full power, we were getting completely blind. They should never let the engineers write the manuals and they should test their manuals with some public before release.
