In experimenting with the Autofocus features on my AC130, I discovered that I was having some difficulty in getting the Face Detection feature to work. I eventually realized that in order to use its Face Detection autofocus feature, that Auto-Iris must also be enabled.
Why is this required? Can anyone here offer an explanation for why this is so?
I noticed that my Canon Vixia HF G10 also has this very same limitation. Its Face Detection will also not work when exposure is in manual mode either. So it would seem that there must be some inherent reason why these two features are linked together.
To be honest, I have not been all that impressed with the Auto-Iris performance on my AC130. So I was hoping that with it I could use Face Detection Autofocus while using a manually set Iris. But it turns out doing that is not an available option.
Since the normal Autofocus can work without Auto-Iris being used, I'm at a loss to understand why using Face Detect Autofocus does.
In the future, it sure would be a real nice feature enhancement if the Face Detection function could be made to work when exposure is being set manually.
