Auto focus mechanism
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.
• For details on compatible lenses, refer to the support site.

* 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]
(page 65) 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.
