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.
- When the F-value is greater than F11, you cannot use the Phase Detection AF. Only Contrast AF is available.
Phase detection AF is available only when an applicable lens is attached. If you use a lens that does not support focal plane phase detection AF, you cannot use [Automatic AF], [AF Track 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.
