Follow the steps below to fine-tune autofocus. Note that fine-tuning applies only with phase-detection AF (viewfinder AF) and is not available during live view. You may have difficulty focusing at infinity or at the minimum focus distance while fine-tuning is in effect.

To delete previously-saved values, select List saved values, highlight the desired lens, and press .
Checking Focus
Photograph the target as described in “Setup” and check focus (if the effect is hard to see in the camera monitor, transfer the picture to a computer, where it can be viewed at higher resolution).
