Hybrid Phase Detection AF is active*, you can adjust the autofocus points for the corner areas
(2 - 5) as well as the center area (1).
The adjustment for the center area is applied to both the focal plane phase detection AF
sensor and the dedicated phase detection AF sensor.
The adjustments for the corner areas are applied to the focal plane phase detection AF
sensor.
When a lens that supports Hybrid Phase Detection AF is attached, and [AF System] is set to [Auto]
*
Hint
It is recommended that you adjust the position under actual shooting conditions. Set [Focus Area] to
[Flexible Spot] and use a bright subject with high contrast when you adjust.
Note
For focal lengths between the wide end and the telephoto end, the values interpolated by the values
for each end are applied.
For areas between the adjusted areas, the values interpolated by the values for each area are
applied.
When the focal plane phase detection AF area is narrowed, such as when an APS-C size dedicated
lens is attached, the adjustable area is the narrowed AF area only.
When a prime lens is attached, you cannot enter the adjustment value for the telephoto end. The
adjustment value for the wide end is applied.
You cannot adjust the autofocus position for the corner areas in following situations:
[Selectable AF Area] is set to [Only Cross-Type AF]
[Flexible Spot Points] is set to [15 Points]
When you attach a lens for which you have already registered a value, the registered value appears
on the screen. [±0] appears for lenses for which a value has not yet been registered.
If [-] is displayed as the value, then a total of 30 lenses have been registered and no new lens can be
registered. To register a new lens, attach a lens for which the registration can be erased, and set its
value to [±0], or reset the values of all the lenses using [Clear].
The [AF Micro Adj.] supports Sony, Minolta, or Konica-Minolta lenses. If you perform [AF Micro Adj.]
with lenses other than the supported lenses, the registered settings for the supported lenses may be
affected. Do not perform [AF Micro Adj.] with an unsupported lens.
You cannot set [AF Micro Adj.] individually for a Sony, Minolta, and Konica-Minolta lens of the same
specification.
