# isLockingFocusWithCustomLensPositionSupported

A Boolean value that indicates whether the device supports locking focus to a specific lens position.

## Declaration

```swift
var isLockingFocusWithCustomLensPositionSupported: Bool { get }
```

## Discussion

Discussion If this property’s value is false, calling the setFocusModeLocked(lensPosition:completionHandler:) method with a lens position value other than currentLensPosition raises an exception.
