Focal plane phase detection AF
When there are focal plane phase detection AF points within the auto focus area, the product uses the combined autofocus of the focal plane phase detection AF and contrast AF.
Note
- When the aperture value is set to F13 or above, you cannot use the focal plane phase detection AF. Only contrast AF is available.
- Focal plane 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 Duration] or [
AF drive speed].
Also, even if you use a previously purchased applicable lens, the focal plane phase detection AF might not function unless you update the lens. For details on applicable lenses, refer to the support page:
