Fine adjustment of the AF’s point of focus is possible for viewfinder
shooting. This is called “AF Microadjustment”. Before making the
adjustment, read “General Cautions for AF Microadjustment” on page
432.
Set the adjustment amount manually by repeatedly making
adjustments, shooting, and checking the results until the desired result
is achieved. During AF, regardless of the lens used, the point of focus
will always be shifted by the adjustment amount.
