K&F ConceptCPL Filter Compatible with DJI Mini 4 Pro, CPL Polarizer Filter, Secure Attach/Multi Coated HD Optical Glass/Lightweight Frame

I tried one other, did not get a good fit. It does exactly what a CPL should do, give good contrast enhancement and help saturate colors. It does also function as a small amount of ND to help in daytime video, about 1.5 stops. I like it and it is not too terribly overpriced as well.

This K&F Concept polarizing filter is a necessity for my DJI Mini 4 Pro! I never take it off – it's become an essential part of my drone setup. The colors are more vibrant, the skies are deeper blue, and reflections are minimized. It’s easy to install and doesn’t affect the drone's performance. This filter is a must-have!

Fits perfect on my DJi drone and works like it should

Comes in a medium sturdy plastic case that also works to keep original lens. I like that. It fits easily and snug on the camera with a twist rotation. I like that too. Looks and feels strong. Took it out to the pond and was a bit underwhelmed. It seems to reduce the glare on the water surface some. But not all. As I spin the wheel on the lens slowly, part of the screen gets clear, while the other side of the image/still glares. So... Apparently for water glare there must be better CPL's. Blue sky was excellent and much better than original lens. A strong disappointment was not getting a lens cover for it. I only shoot outside here in Hawaii and plan to leave it on, risking lens coating damage. Conclusion: 4 stars good for casual shooter but not recommended for professional results.

K & F what more can I say! I like their quality and the fact they do exactly what I bought it for.

Not sure what this filter is for, maybe some sort of smart phone, but definitely not compatible with DJI mini.
