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 111.
Normally, this adjustment is not required. Do this adjustment 
only if necessary. Note that doing this adjustment may prevent 
correct focusing from being achieved.
Set the adjustment manually by adjusting, shooting, and checking the 
result. Repeat this until the desired adjustment is made. During AF, 
regardless of the lens used, the point of focus will always be shifted by 
the adjustment amount.
