Fine-tune focus for the current lens.
-
Use only as required.
-
We recommend that you perform fine-tuning at a focus distance you use frequently. If you perform fine-tuning at a short focus distance, for example, you may find it less effective at longer distances.

Creating and Saving Fine-Tuning Values

The current value is shown by g, the previously-selected value by j.
-
If a zoom lens is attached, you can choose separate fine-tuning values for maximum angle (WIDE) and maximum zoom (TELE). Use 1 and 3 to choose between the two.
-
The larger the fine-tuning value, the farther the focal point is from the lens; the smaller the value, the closer the focal point.
-

Press J to save the new value.
You can fine-tune autofocus automatically while viewing the results in the live view display (Auto AF Fine-Tuning). Pressing the W (M) button in Step 3 takes you to Step 2 of “Auto AF Fine-Tuning”.

Auto AF fine-tuning works best at maximum aperture.

If auto fine-tuning fails, a message will be displayed. Press X to attempt auto fine-tuning again, or press J to exit without performing AF fine-tuning. Pressing X returns you to Step 2.
If a fine-tuning value exists for the current lens, you can choose to overwrite the existing value or save the new value separately in Step 2.
