Fine Adjustment of AF's Point of FocusN
3
Fine adjustment of the AF's point of focus is possible for viewfinder
shooting and Live View shooting in the Quick mode. This is called "AF
Microadjustment". Before making the adjustment, read "Notes for AF
Microadjustment" on page 110.
Normally, this adjustment is not required. Do this adjustment
only if necessary. Note that doing this adjustment may prevent
correct focusing from being achieved.
Adjust All by Same Amount
Set the adjustment manually by adjusting, shooting, and checking the
result. Repeat this until the desired adjustment is made. During AF,
