Hi gang, I've had my D3 a bit over five years now. Last year it developed a focus problem. Sometimes I'd lift the camera to focus on something, press AF-ON, and nothing would happen (I long ago shut off focusing with the shutter button, and the camera's always on continuous focus and release). Other times autofocus would take place at once. Sometimes I'd lock on to something, track it, and the camera would lose focus part way through the tracking. Sometimes it would stay locked. It wasn't a lens problem because all my lenses were focusing perfectly with my D800. It's not an AF-ON button problem because I switched shutter focus back on and tested with that for a while. No change.
In early December the problem became severe enough that there were more misses than hits with the D3, so I sent the camera to Nikon for repair. Got it back yesterday. The situation's improved but the problem's not gone completely.
I'm not sure whether or not to send the camera in a second time. Happily I have a couple months to make that decision. Has anybody else had the problem I'm having? If so, what was the final outcome?

I have not had any problems with my D3 or D3s.
Test your camera and if the problem persists, send it back to Nikon Service. It makes no sense to continue using a camera that doesn't work properly.
Good Luck and Enjoy your Nikons!

Thanks, Marty. I took the camera downtown yesterday with a 28-300 on it and did some fairly extensive shooting. Most of the time the camera would autofocus properly, but every now and then it would hang. Of course the hang always comes at the worst possible moment. Later in the evening I picked up the camera again and found that with the 28-300 on it, autofocus has failed completely. I tried some of my other zooms on it and all of them gave me mixed results -- autofocusing sometimes and failing other times. Finally I tried the 28-300 on my D800 and found that its autofocus was dead on that camera too. Now I'm afraid to try my other lenses on the D3 for fear the body will clobber them too.
I explained all this to Nikon this morning. I'm sure I'm going to be sending the body and the 28-300 in for repair. At least this time both the body and lens are under warranty.
Worst thing is that I have a shoot scheduled early next month for the dress rehearsal of a play. I did the last one with the D800, and the post-processing work just about did me in. I want to do that shoot with the D3. My fingers and toes are crossed.
Edit: Camera and lens are on their way back to Nikon. We'll see what happens next.
