So I have a few questions about filters for the DJI Air 2S. I got the normal package but do intend to buy a couple of extra batteries (that's all from the fly more package I really feel that I need). However, I'd like to have some filters on hand just in case I need them. So my question is: should I go with DJI's filters and buy one from someone who actually did get the Fly-More-Combo but don't want the filters or should I go with some other vendor like Freewell or PolarPro? Also, what range of filters would it be best to have. I think the DJI filters go from ND 4 to ND 32 so would I need a 64 filter too? Sorry if this has already been discussed. I haven't seen any threads on it so far. Thanks!
