Filters of excellent optical quality, as always I must say from K&F.

I measured a weight of 3.8 grams, just 0.3 grams above the declared value, and in any case no hesitation from the gimbal.

I tried to point the cam against the sun, both the wide angle and the telephoto, without having any additional reflection (the Dji lens itself has a bit of flare). Sharpness unchanged, absolutely perfect glass.

I preferred them to the originals for the attenuation values ​​better spaced compared to the DJI kit, but compared to the originals these do not have the double ND value: the original filters have half the ND value on the telephoto lens only, in order to have the exposure values ​​absolutely aligned between the two lenses.

It may seem like a small thing, and if you think about it well without a filter in fact the exposure values ​​are NOT aligned because the telephoto is a 2.8, but it would have been a very convenient addition, which the original filters have. and yet in the original kit the steps go by two at a time, a bit too much, with an ND 128 that is excessive in my opinion. the final rating I would give to this kit is between 4 and 5 stars, but closer to 5. and then in fact a truly complete alternative does not exist.

All things considered I can only recommend this kit. Sharp images, no reflections, attenuation value perfectly aligned with what is declared.
