AF Fine-Tuning Options

G button UB setup menu

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 focus-tuning at a short focus distance, for example, you may find it less effective at longer distances.

Option	Description
[AF fine-tune]	Select [ON] to turn fine-tuning on.
[Fine-tune and save lens]	Fine-tune focus for the current lens. Press 1 or 3 to highlight items and press 4 or 2 to choose from values between +20 and −20. The larger the fine-tuning value, the farther the focal point is from the lens; the smaller the value, the closer the focal point. The display shows the current and previous values. The camera can store values for up to 40 lens types. If a value already exists for the current lens, you can choose whether to add a new value or overwrite the existing value.
[Default]	Choose the fine-tuning values for lenses for which no values have previously been saved using [Fine-tune and save lens]. Press 4 or 2 to choose from values between +20 and −20.
[List saved values]	List values saved using [Fine-tune and save lens]. Highlighting a lens in the list and pressing 2 displays a [Choose lens number] dialog. The [Choose lens number] dialog is used to enter the lens identifier. In the case of Z mount lenses and some F mount lenses, the lens serial number is entered automatically.
[Choose value for current lens]	Choose from multiple fine-tuning values saved for lenses of the same type.

Deleting Saved Values

To delete values saved using [Fine-tune and save lens], highlight the desired lens in the [List saved values] list and press O (Q).
