Fine Adjustment of AF’s Point of Focus

<

amount ] and [ Adjust by lens ].
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 position, and other shooting conditions.
Therefore, even if you perform AF Microadjustment, focus may still not
be achieved at the 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 the 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 (compression) to 8 or higher is
recommended.
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.
AF adjustment is not possible for Live View shooting’s [ Live mode ] and
[
u
Live mode ] (contrast AF).
