3 Fine Adjustment of AF’s Point of FocusN
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 position, 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 adjustment 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.
