Interchangeable Lens Digital CameraILCA-99M2α99II

This camera 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. Use lenses that support the Hybrid Phase Detection AF system for a wide area, high density, multiple points, and Hybrid Cross AF Points*¹, which are difficult to achieve with just a single dedicated phase detection AF sensor.

^*1 In Hybrid Cross AF points, the focal plane phase detection AF sensor and dedicated phase detection AF sensor work together. These points have a superior capturing ability and can achieve high-accuracy focusing.

Auto focus area in Hybrid Phase Detection AF

The Hybrid Phase Detection AF system is active when a lens that supports the Hybrid Phase Detection AF system is attached and [AF System] is set to [Auto]. The Hybrid Phase Detection AF system allows you to use an auto focus function with a wide area, 399 focus points (maximum), and Hybrid Cross AF. 323 focus points are selectable.

Focal plane phase detection AF (vertical detection) + dedicated phase detection AF (cross detection*², F2.8-sensitive)

Focal plane phase detection AF (vertical detection) + dedicated phase detection AF (horizontal detection)

(D): Focal plane phase detection points (vertical detection)

^*2 Cross detection focus points achieve high capturing performance by arranging horizontal detection points and vertical detection points in a cross shape in the same focusing area. The focus point at the center is also equipped with a F2.8-sensitive sensor that supports lenses with a minimum F-value of 2.8 or lower.

Auto focus area of the dedicated phase detection AF sensor

The dedicated phase detection AF sensor with 79 focus points is used for auto focusing when a lens that does not support the Hybrid Phase Detection AF system is attached, or [AF System] is set to [Ddc Phase AF Only].

• The number of focus points is limited to 61 in the movie shooting mode.
