You can make fine adjustments for the AF’s point of focus. For details, 
see “Fine Adjustment of AF’s Point of Focus” on the next page.
AF Microadjustment 
						

							134
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” on page 
139.
Set the adjustment manually by adju sting, shooting, and checking the 
result. Repeat this until appropriate adjustment is made. 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 [2 5] tab, select [AF 
Microadjustment ], then press .
2Select [All by same amount].
3Press the  button.
The [ All by same amount ] screen 
will appear.

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 whose adjustment is registered, the 
point of focus will always be shifted by the adjustment amount.
Set the adjustment manually by adjusting, shooting, and checking the 
result. Repeat this until the desired adjustment is made. If you use a zoom 
lens, make the adjustment for the wide-angle (W) and telephoto (T) ends.
1Select [Adjust by lens].
2Press the  button.
The [ Adjust by lens ] screen will 
appear.
3Check and change the lens 
information.
Checking the Lens Information

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, 
see the next page.

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.
 Some lenses may not have a serial 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 Extender 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.

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 stop 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 during Live View shooting or 
movie shooting.
 The adjustments will be retained even if you clear all the camera settings 
(p.70). 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 can fail to achieve focus (viewfinder’s focus indicator  
blinks) with certain subjec ts 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.)
 Repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
In such cases, focus by doing either of the following:
(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.83).
(2) Set the lens’s focus mode switch to < MF> and focus manually 
(p.141).
When Autofocus Fails
 Depending on the subject, focus  may be achieved by slightly 
recomposing the shot and performing AF operation again.
 For conditions where AF can fail to achieve focus with [ u+Tracking ]/
[ FlexiZone - Single ] during Live View shooting or movie shooting, see 
page 273.
