Review on Enhanced Air 2S Drone Compatibility: Freewell Variable VND Filter covering 2-5 Stops and 6-9 Stops by Owen Houser

I have several Freewell products but unfortunately they don't stay in my bag. They have very strong vignetting at every stop. At foot 5, in bright sunlight, I have vignetting right down the center and the rest of the feet to the left or right. Also they are very heavy, several times I was up and didn't want to go down to remove the filter. so I would just adjust the shutter speed to take a panorama. They are so heavy that panoramas with them do not result in an even horizon, they are all strongly curved. I would send them back, but unfortunately the return period has expired, they just sit in the desk drawer.
