Fine Adjustment of AF Position (AF Microadjustment)
2: Adjust by Lens
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.
