The UV filter on the P3A & P3P come off, it doesn't on the P3S and I don't know about the P3 4k. Would kinda suck if the P3 4k didn't have a removeable UV filter.
Tru dat. Unless it's pretty much dark, my Polarized filter is on... usually a ND 8 in sunny Fla.. If you're flying for the
sake of photographing, an interchangeable filter isn't an option. It's pretty much a "must".
