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*
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.
