When a CPU lens is mounted on the camera, autofocus can be manually or (in live view) automatically fine-tuned to suit your preferences. In the case of zoom lenses, the camera can store two fine-tuning values for each lens: one for use when the lens is zoomed all the way out (WIDE) and another for when it is zoomed all the way in (TELE).
To fine-tune autofocus for the current lens, select [AF fine-tuning options] > [Fine-tune and save lens] in the setup menu. Any previously-saved value for the current lens will be overwritten.
1 Select [Fine-tune and save lens].
In the setup menu, select [AF fine-tuning options], then highlight [Fine-tune and save lens] and press to display the AF fine-tuning dialog. The options displayed vary with the type of lens.
To fine-tune autofocus automatically while previewing the results in live view:
1 Ready the camera.
Mount the camera on a tripod and aim it at a flat, high-contrast subject parallel to the camera focal plane. Note that auto AF fine-tuning works best at maximum aperture and may not function in dark surroundings.
3 Start auto AF fine-tuning.
Press the AF-mode and movie-record buttons and keep them pressed until fine-tuning options are displayed.
Fixed focal-length (prime) lenses: If the current lens is a prime lens, the camera will display the fine-tuning dialog with the center focus point selected.
If you are fine-tuning a zoom lens, you will need to repeat the process to save a value for the remaining zoom position (WIDE or TELE). Press , select [Overwrite value for existing lens], and return to Step 3.
To delete a saved value when it is no longer needed, highlight the lens in the list and press .
