I'm trying to make an application that uses the AVCaptureDeviceTypeBuiltInDualCamera cameras.
When the auto focus is enabled on AVCaptureDeviceTypeBuiltInDualCamera, it seems that the focus is made on the AVCaptureDeviceTypeBuiltInWideAngleCamera. I know that they are some constraints on a dual setup for the focus.
In some cases, the focus is correct AVCaptureDeviceTypeBuiltInWideAngleCamera and really bad on AVCaptureDeviceTypeBuiltInTelephotoCamera. Is there a way to indicate that we prefer having a correct focus on the AVCaptureDeviceTypeBuiltInTelephotoCamera instead of AVCaptureDeviceTypeBuiltInWideAngleCamera ?
