Panasonic 4/3rd Lens Not Recognized

I just purchased the Panasonic H-FS045200 to use with my BMPCC4k. Except the BM will not even register that a lens is connected. No iris control, the focus ring does not work at all either. I have two BMPCC4k's that I use fr streaming, and my other Panasonic lenses work fine. Any ideas? Everything is updated to the latest firmware including the lens. It does work fine with a GH5.

Any suggestions would be appreciated.

Try downgrading the camera to a version 6.xx firmware.

So the downgrade seemed to work, I'm going to try again to upgrade and see if somehow it works again. Thanks for the suggestion. I at least have that option.

It won't work with the new firmware, it's a known problem with some lenses.
