Hi,
with the strange shape of the Mavic 3 camera (btw I wonder how many among the owners of the Mavic 3 will really use this "telelens") I am afraid that neither DJI nor third parties will be abble to design CPL polarization filters.
I hope I am wrong... but if not it would be a real disadvantage (maybe the only one, if we exclude the price...) compared to the "old" Mavic 2.

The drone comes with a set of filters so Im sure it will be easy for the manufactures like freewill and polar pro to copy that mount.   They did it for the M2P and that was a unique camera too.

I have sent the question to PolarPro and Freewell: we'll see

They are both great companies and I have no doubt they will be able to manufacture CPL polarization filters for the Mavic 3.
