I meant "good luck" as in the DJI filters are SO lightweight that I'm sure they have almost NO effect on the fragile, delicate, lightweight gimbal motor, the way some of the heavier "slip-on" style of filters often do. They do a good job of filtering the light the way they're supposed to, they're affordable, and they're easy to take on and off. My videos look better when using them. It is a trade-off. Being so lightweight, I could see where they would be easier to break over time, or easier to lose.
I agree with ed1nh0, in that the Taco filters are good (for double the price) and more durable, but they are heavier and will put a little more strain on the gimbal motor. I change the lens on my very frequently, because I fly frequently under varying lighting conditions.
After talking to a local drone repair tech who has worked on dozens of mavics, he said that ANY extra weight on the gimbal motor is going to have a detrimental effect in the long term - you're going to wear it out faster - that gimbal is already so tiny and delicate and lightweight. He said he wouldn't use any brand on his mavic other than the DJI's, even though they ARE more delicate than the heavier brands. Also, most of the slip-on style filters take a little more effort to push on and pull off, putting extra strain on your gimbal each time, which, again, probably isn't good long term.
I decided, for me, that I'd rather risk having to replace a $35 set of lens filters some day than have to replace a $500 gimbal assembly someday.
That being said, I cannot speak to how much better? the heavier Taco or Polar Pro brand lenses are as far as picture quality. I'm sure they make great videos and are very high quality. I've never heard anyone complain about the quality of either brand. The DJI lenses are NOT polarized, FYI, if that's important to you.
Just my .02 cents.
