Fine adjustment of the AF’s point of focus is possible for viewfinder 
shooting and in Live View shooting’s [ Quick mode]. This is called “AF 
Microadjustment”. Before making the adjustment, read “Notes for AF\
 
Microadjustment” on page 107.
Normally, this adjustment is not required. Do this adjustment 
only if necessary. Note that performing AF Microadjustment 
may prevent correct focusing from being achieved.
Set the adjustment value manually by  adjusting, shooting, and checking 
the result. Repeat this until the desir ed adjustment is made. During AF, 
regardless of the lens used, the poin t of focus will always be shifted by 
the adjustment amount.

Notes for AF Microadjustment
Clearing All AF Microadjustment data
 The AF’s point of focus will vary  slightly depending on the subject 
conditions, brightness, zoom positi on, and other shooting conditions. 
Therefore, even if you perform AF Microadjustment, focus may still not 
be achieved at th e suitable position.
  The adjustment data will be retained  even if you clear all the camera 
settings (p.58). However, the setting itself will be [ Disable].
 It is best to make the adjustment at  the actual location where you will 
shoot. This will make th e adjustment more precise.
  Using a tripod when making the adjustment is recommended.
  To check the result of the adjustment, setting the  image size to JPEG L 
(Large) and the JPEG quality (com pression) to 8 or higher is 
recommended.
  The adjustment amount of one step  varies depending on the maximum 
aperture of the lens. Ke ep adjusting, shooting, and checking the focus 
repeatedly to adjust th e AF’s point of focus.
  AF adjustment is not possible  for Live View shooting’s [Live mode] and 
[ u  Live mode ] (contrast AF).

Autofocus can fail to achieve focus (the viewfinder’s focus confirmation 
light < o> blinks) with certain subjects such as the following:
Subjects difficult to focus
  Very low-contrast subjects
(Example: Blue sky, solid-color walls, etc.)
  Subjects in very low light
  Extremely backlit or reflective subjects
(Example: Car with a highly reflective body, etc.)
  Near and far subjects covered by an AF point 
(Example: Animal in a cage, etc.)
  Repetitive patterns
(Example: Skyscraper windows,  computer keyboards, etc.)
In such cases, do either of the following:
(1) With One-Shot AF, focus on an obj ect at the same distance as the 
subject and lock the focus before recomposing (p.67).
(2) Set the lens focu s mode switch to  and focus manually (p.109).
