You can register adjusted values of [AF Micro Adj.].

Select the desired value with v/V on the multi-selector, then press the center of the multi-selector.

Notes

•When [AF Micro Adj.] is not set to [On], you cannot register an adjustment value.

•By shifting the value toward +, the focus point shifts toward the background, and by shifting it toward –, the point shifts toward the foreground. Decide the value by reference to the result of a test shooting.

•We recommend that you decide the value under actual shooting conditions.

•When you attach a lens that is registered on the camera, the registered value is displayed. When you attach an unregistered lens, “±0” is displayed. If “–” is displayed as the value, then a total of 30 lenses have been registered. When you want to register a new lens, attach a lens for which you can delete its registered value, and set that value to “±0,” or reset the values of all the lenses with [Clear].

•If you perform AF fine adjustment with a lens of other manufacturers, the adjustment values of Sony, Minolta, and Konica Minolta lenses may be affected. Do not use this function with any lens of other manufacturers.

•You cannot individually perform AF fine adjustment when using the Sony, Minolta, and Konica Minolta lenses that have the same specifications.
