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.
