You can make the adjustment for each lens and register the adjustment 
in the camera. You can register the adjustment for up to 40 lenses. 
When you autofocus with a lens whose adjustment is registered, the 
point of focus will always be shifted by the adjustment amount.
Set the adjustment amount manually by repeatedly making 
adjustments, shooting, and checking the results until the desired result 
is achieved. If you use a zoom lens, make the adjustment for the wide-
angle (W) and telephoto (T) ends.
