A Boolean value that determines whether the device has smooth autofocus enabled.
- iOS 7.0+
- Mac Catalyst 13.0+Beta
On capable devices, you can enable a “smooth” focusing mode in which the camera makes lens movements more slowly. This mode make focus transitions less visually intrusive, a behavior that you may want for video capture.
Before changing the value of this property, you must call
lock to acquire exclusive access to the device’s configuration properties. Otherwise, setting the value of this property raises an exception. When you finish configuring the device, call
unlock to release the lock and allow other devices to configure the settings.
