Fine-tune focus for up to 20 lens types. Use only as required; AF tuning is not recommended in most situations and may interfere with normal focus. Auto fine-tuning is available in live view (0 Auto AF Fine-Tuning). We recommend that you perform fine-tuning at a focus distance you use frequently; if you perform focus-tuning at a short focus distance, for example, you may find it less effective at longer distances.
Live View Photography
Tuning is not applied to autofocus during live view photography.
Only one value can be stored for each type of lens. If a teleconverter is used, separate values can be stored for each combination of lens and teleconverter.
Auto AF Fine-Tuning
Auto AF fine-tuning is performed as described below.
Ready the camera.

Adjust focus settings.

Press J to select the center focus point.
Press the shutter-release button halfway to focus, then zoom in on the view through the lens to confirm that the subject is in focus. Focus can be adjusted manually if necessary.
Perform auto AF fine-tuning.
Press the AF-mode and movie-record buttons simultaneously and keep them pressed until the dialog shown in Step 7 is displayed (this should take slightly over two seconds).
