Viofo doesn't know for sure!
Tell me, which filter CPL is EXACTLY, 100% suitable for the rear camera?
Thank you in advance.

As far as I know Viofo doesn't make a CPL filter for the rear/internal camera of the 139 Pro.

The rear or interior camera don't even have the mounting to attach a CPL.

I have glued the A119 mini CPL to my “rear” Camera (used as front telephoto)
