been flying my Mavic Air 2S for about a year now and i keep seeing people recommend ND filters pretty heavily but the PolarPro sets are like $100+ and there are random Amazon sets for $20 that have like 10 filters in them. genuinely cant tell if the price difference matters or if its one of those things where the gear community just defaults to expensive stuff

i mostly shoot landscape stuff, nothing professional, just personal use and occasionally stuff for friends. so its not like im getting paid for this. but i do care about the footage looking decent

i bought a cheap set a few months ago and honestly they seem fine to me but i also dont have anything to compare them to so i have no idea if im missing something. someone at a meetup told me the cheap ones can cause color casts but i havent really noticed anything obvious

honestly for personal use the cheap ones are probably fine. the color cast thing is real but its usually pretty subtle and easy enough to correct in post if you shoot in any kind of log profile. where the more expensive filters like PolarPro really earn their price is consistency across the set and the coatings being more resistant to flare and ghosting, which matters a lot more if youre shooting into the sun or doing paid commercial work where a client might notice

ive used both and for casual landscape shooting i genuinely would not stress about it. spend the money on a spare battery instead

i went through like three cheap Amazon sets before just buying the PolarPro Cinema Series and the difference was noticeable for me but i was also doing some real estate video work so it made sense cost wise. for just personal flying i think you'd be totally fine sticking with what you have, the 2S sensor is good enough that small filter differences arent gonna make or break your footage
