Hybrid Phase Detection AF system

Auto focus area settings

ILCA-99M2 is equipped with a Hybrid Phase Detection AF system simultaneously driven by a focal plane phase detection AF sensor and a dedicated phase detection AF sensor.With a Hybrid Phase Detection AF system compatible lens, you can use Hybrid Cross AF Points that measure the range using these 2 AF sensors.

Hybrid Phase Detection AF system

AF when using a compatible lens

By setting [AF System] of  (Camera Settings1) to [Auto], and switching [Selectable AF Area] to [Auto] or [Only Cross-Type AF], you can set to an AF area that suits your preference.

Go <here> if [AF System] is set to [Ddc Phase AF Only].

[AF System]: When set to [Auto]

Selectable AF Area AF Area (Conceptual diagram) Features
Auto In addition to Hybrid Cross AF Points, this setting uses a focal plane phase detection AF sensor positioned in wide range and high density. It is possible to measure a wider area in high density and multiple points compared to the dedicated phase detection AF sensor.
Only Cross-Type AF A setting that uses only Hybrid Cross AF Points. By limiting to the AF area that simultaneously detects both horizontal detection and vertical detection, it is less affected by the subject pattern and is superior in focusing performance.

Refer to the following for the features of each Focus Area depending on the [Selectable AF Area] settings when [AF System] is set to [Auto].

Wide

Selectable AF Area AF Area (Conceptual diagram) Features
Auto Automatically selects which area will be used for focus of 399 AF points at maximum. Effective for scenes with intense movement in a wide range.
Only Cross-Type AF Focuses with 79 Hybrid Cross AF Points at maximum. Uses only the Hybrid Cross AF Points in the center of the monitor and is superior in focusing performance.

Zone

Selectable AF Area AF Area (Conceptual diagram) Features
Auto Select a zone on the monitor on which to focus. You can choose among 15 zones. The area for focus in the chosen zone is automatically selected.
Only Cross-Type AF Select a zone on the monitor on which to focus. You can choose among 9 zones. The area for focus in the selected zone is automatically selected.The selectable AF area only uses Hybrid Cross AF area so it is superior in focusing performance.

 Center
Focuses automatically on a subject in the center of the monitor. Use together with the focus-lock function to create the composition you want.

Flexible Spot

Allows you to move the focusing frame to a desired point on the AF area and focus on an extremely small subject or a narrow area.

Selectable AF Area Flexible Spot Points AF Area (Conceptual diagram) Features
Auto All Selectable from 323 AF points at maximum. Effective for shooting landscape scenes with a composition of your preference or portraits.
63 Points Of the 323 AF points at maximum, the AF point is selectable from the limited 63 AF points, and by positioning the subject fully on the monitor, the AF points can be swiftly switched. Effective for shooting subjects that largely change positions in the screen such as airplanes, birds, etc.
15 Points Selectable from the 15 Hybrid Cross AF Points limited to the center area and can swiftly switch the AF points to the subject in the monitor. Effective for shooting soccer matches, motor sports, etc. where subjects move rapidly left and right. The selectable AF area only uses Hybrid Cross AF area so it is superior in focusing performance.
Only Cross-Type AF All Since you can select from 79 Hybrid Cross AF Points at maximum, it is recommended to shoot scenes composed that suit your preference by placing the subject in the center and performing detailed adjustments of the AF points.

 Expand Flexible Spot
If the product cannot focus on a single selected point, it uses AF points around the flexible spot as a secondary priority area for focusing.
Expand Flexible Spot Points can be selected as with Flexible Spot above. Please refer to the description of Flexible Spot.

     Lock-on AF
[Lock-on AF] is recommended to shoot while staying focused on a subject and while freely changing framing. (This setting is available only when [Focus Mode] is set to [Continuous AF].) Press the shutter button halfway to start tracking. To specify where to start tracking, choose among Focus Area selections: [Center] or [Flexible Spot] (both have a narrow focus area) for subjects moving slowly when tracking starts; [Expand Flexible Spot] for normal subject movement; and [Zone] or [Wide] for higher focusing performance when the subject moves intensely within frame. After lock-on, focusing is not dependent on the selected Focus Area, and keeps focusing in the same area as the [Wide] tracking range.

AF when using a non-compatible lens

If a Hybrid Phase Detection AF system non-compatible lens is attached or [AF System] is set to [Ddc Phase AF Only], the AF areas become the following.
