Actually, this is his 3rd Nikon, and I've had a D600 since September, so we are pretty sure we were using the adjustment correctly. It has about 9 "clicks" and for both of us about 2 "clicks" from the center will "focus" the viewfinder to our eyes (without needing our "cheater reader" 1.5 magnification glasses, though they are helpful when looking at live view and LCD image displays).

I recall someone in Italy on a forum with this issue and interestingly my now returned and exchanged first D600 refused to adjust at ALL twice - though I exchanged it for a different reason - it occasionally went black and refused to operate.
