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 [Automatic AF], [

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.
