Fine adjustment of the AF’s point of focus is possible for viewfinder 
shooting. This is called “AF Mi croadjustment”. Before making the 
adjustment, read “General Cautions  for AF Microadjustment” and 
“Notes for AF Microadjustment” on page 157.
Set the adjustment amount m anually 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.
1Select [AF Mi croadjustment].
 Under the [ 25] tab, select [ AF 
Microadjustment ], then press .
2Select [All by same amount].
3Press the < B> button.

4Make the adjustment.
 Set the adjustment amount. The 
adjustable range is ±20 steps.
  Setting it toward “-: ” will shift the 
point of focus in front of the standard 
point of focus.
  Setting it toward “+: ” will shift the 
point of focus to behind the standard 
point of focus.
  After making the adjustment, press 
.
  Select [ All by same amount ], then 
press < 0>.
5Check the result of the 
adjustment.
  Take a picture and play back the 
image (p.394) to check the 
adjustment result.
  If the shooting result comes out with 
focus in front of the targeted point, 
adjust toward the “+: ” side. If it 
comes out with focus behind the 
targeted point, adjust toward the 
“-: ” side.
  If necessary, repeat the adjustment.
If [All by same amount ] is selected, separate AF adjustment will not be 
possible for the wide-angle and telephoto ends of zoom lenses.

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 w hose adjustment is registered, the 
point of focus will always be shifted by the adjustment amount.
Set the adjustment amount m anually 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.
1Select [Adjust by lens].
2Press the < B> button.
XThe [ Adjust by lens ] screen will 
appear.
3Check and change the lens 
information.
Displaying the Lens Information
  Press the < Q> button.
X The screen will show the lens name 
and a 10-digit serial number. When 
the serial number is displayed, select 
[OK ] and go to step 4.
  If the lens’s serial number cannot be 
confirmed, “0000000000” will be 
displayed. In this case, enter the 
number by following the instructions 
on the next page.
  Regarding the asterisk “ * ” displayed 
in front of some lens serial numbers,

Entering the Serial Number
 Select the digit to be entered, then 
press < 0> so < r> is displayed.
  Enter the number, then press < 0>.
  After entering all the digits, select 
[OK ].
Lens Serial Number
 In step 3, if “ * ” appears in front of the 10-digit lens serial 
number, you can register only one unit of the same lens model. 
Even if you enter the serial number, “ * ” will remain displayed.
  The serial number on the lens may differ from the serial number 
displayed on the screen in step 3. This is not a malfunction.
  If the lens serial number includes letters, enter only the numbers.
  If the lens serial number is eleven  digits or longer, enter only the last 
ten digits.
  The location of the serial number  varies depending on the lens.
  Certain lenses may not have a seri al number inscribed. To register a 
lens that has no serial number in scribed, enter any serial number.
 If [Adjust by lens ] is selected and an exten der is used, the adjustment 
will be registered for the lens and extender combination.
  If 40 lenses have already been registered, a message will appear. After 
you select a lens whose registration is to be erased (overwritten), you 
can register another lens.

 For a zoom lens, select the wide-
angle (W) or telephoto (T) end. 
Pressing < 0> will turn off the purple 
frame and make the adjustment 
possible.
  Set the adjustment amount, then

  Setting it toward “-: ” will shift the 
point of focus in front of the standard 
point of focus.
  Setting it toward “+: ” will shift the 
point of focus to behind the standard 
point of focus.
  For a zoom lens, repeat this 
procedure and adjust it for the wide-
angle (W) and telephoto (T) ends.
  After completing the adjustment, 
press the < M> button to return to 
the screen in step 1.
  Select [ Adjust by lens ], then press 
< 0 >.

image (p.394) to check the 
adjustment result.
  If the shooting result comes out with focus in front of the targeted 
point, adjust toward the “+: ” side. If it comes out with focus behind 
the targeted point, adjust toward the “-: ” side.
  If necessary, repeat the adjustment.

When [  Clear all] appears at the bottom of the screen, pressing the 
< L > button will clear all the adjustments made for [ All by same 
amount ] and [Adjust by lens ].
Clearing All AF Microadjustments
When shooting with the intermediate range (focal length) of a zoom lens, the 
AF’s point of focus is corrected automatically relative to the adjustments 
made for the wide-angle and telephoto ends. Even if only the wide-angle or 
telephoto end is adjusted, a correction will be made automatically for the 
intermediate range.
General Cautions for AF Microadjustment
 The AF’s point of focus will vary slightly depending on the subject 
conditions, brightness, zoom posit ion, and other shooting conditions. 
Therefore, even if you perform AF  Microadjustment, focus may still not 
be achieved at the suitable position.
  The adjustment amount of one step varies depending on the maximum 
aperture of the lens. Keep adjusting, shooting, and checking the focus 
repeatedly to adjust the AF’s point of focus.
  The adjustment will not be applied to AF in Live View shooting or movie 
shooting.
  The adjustments will be retained even if you clear all the camera settings 
(p.77). However, the setting itself will be [ Disable].
Notes for AF Microadjustment
 It is best to make the ad justment at the actual location where you will 
shoot. This will make the adjustment more precise.
  Using a tripod when making the adjustment is recommended.
  For making adjustments, shooting at the  73 image-recording quality is 
recommended.

Autofocus may fail to achieve focus (focus indicator  in the 
viewfinder blinks) with special  subjects such as the following:
Subjects Difficult to Focus
 Subjects with very low contrast
(Example: Blue skies, solid-color flat surfaces, etc.)
  Subjects in very low light
  Strongly backlit or  reflective subjects
(Example: Cars with highly reflective bodies, etc.)
  Near and distant subjects framed close to an AF point 
(Example: Animals in cages, etc.)
  Subjects such as dots of light framed close to an AF point
(Example: Night scenes, etc.)
  Subjects with repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
  Subjects with finer patterns than an AF point
   (Example: Faces or flowers as small as or smaller than an AF point,  etc.)
In such cases, focus in either of the following two ways.
(1) With One-Shot AF, focus on an object at the same distance as the  subject and lock the focus, then recompose the shot (p.101).
(2) Set the lens’s focus mode switch to < MF> and focus manually 
(p.159).
When Autofocus Fails
  Depending on the subject, focus  may be achieved by slightly 
recomposing the shot and performing AF operation again.
  For conditions that make focusing difficult with AF during Live View 
shooting or movie shooting, see page 324.
