properly focus on a subject if you have made a poor adjustment.

Select the desired value
• The larger the value, the farther the focusing position from the camera;
the smaller the value, the nearer the focusing position to the camera.
Notes
• 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. If "–" is displayed as the value, then a total of 30 lenses have been
registered and no new lens can be 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 from the manufactures that are not mentioned
here.
• You cannot individually perform AF fine adjustment when using the Sony, Minolta,
and Konica Minolta lenses that have the same specifications.

Manual focus

When it is difficult to get the proper focus in autofocus mode, you can
adjust the focus manually.
