my 80-499 focuses a lot faster on my D800 than on the D300,


Why? although I haven't tried is it a better motor?

Not sure. I thnk is has to do with the sensor.


The bigger motor, allowed by a better battery.


The D800 has the same battery as the D7000.
I tested D70/90/300/700 using a screw-driven macro lens from closest to
infinity, and the motor drive speed was identical (ie - not just
"close"), despite it being "common knowledge" that the more "pro" bodies
had stronger AF motors.
Sure, the D800 might have a faster AF drive motor, but TBH I doubt it,
as until now Nikon seem to reserve this for pro models with integrated
grip.



batteries should have no effect. The only thing I notice is the
relationship between CCD and CMOS sensors - CMOS uses far less power.

The 800 has a bigger body and may fit a larger more powerful motor. The
D800 is getting very pro'ish

Ill have to check with an old lens to make that comparison with between
D90 D200 D800. the lens that I started to use regularly now is my old
18-35 but didn't take any notice of speed as it was bought back when I
was using a D100 for a wide angle lens.
