GH-5 Autofocus in 4K Live cropping.
 

Since I bought my GH5 I have only shot video using manual focus. I want to try using autofocus and have bought a Leica D6 Vario-Elmar 100-400 to do it. I know about the V2.3 firmware, but haven't installed it .

In reading the manual I see that (page 94) when shooting in 4K live cropping, the only autofocus mode you can use is facial recognition. I shoot a lot of video in 4K live cropping, but only wildlife, never people. Is the camera really not going to let me use other types of autofocus? Sounds pretty ridiculous.

Thanks in advance to anyone who has some experience with this.
