Phase detection AF
When there are phase detection AF points within the auto focus area, the product uses the combined autofocus of the phase detection AF and contrast AF.
Note
-
Phase detection AF is available only when an applicable lens is attached. If you use a lens that does not support phase detection AF, you cannot use [
AF Tracking Sens.], [
AF Tracking Sens.] or [AF drive speed]. Also, even if you use a previously purchased applicable lens, the phase detection AF might not function unless you update the lens. For details on compatible lenses, visit the Sony web site in your area, or consult your Sony dealer or local authorized Sony service facility.
