These are outstanding filters, and this is coming from a filter fanatic. I've been waiting to see K&F get Mini 3 Pro filters out. I have their Mavic 3 VND and Black Mist 1/4 set, and was very impressed with the quality. There's just a solid, quality you can tell by examining the build and the glass is among the best.

I see these as a step up from Freewell, who tries to own the filter market, and Polar Pro, who is looking to be some kind of high end luxury product with the metal cases and gold/brass finished frames. These come in no frills, but functional plastic case with a foam caddy for the filters. I would like yo see K&F deliver a smaller, more appropriate case for filters that are equal or better than Polar Pro's filters.

Delivering new drone filters does not mean inexperience in manufacturing top quality glass. K&F makes hundreds of multi-coated top level camera filters, as well as telescopes, binoculars and other photography gear. They are no stranger to making a quality filter, and these are no exception. Unlike another review, I only had a soft fit on the UV filter; all of the ND/PL filters fit snug and consistently, and I am very happy with these.

The frames are made of "aerospace aluminum" - and are substantial lighter than my Polar Pro FX filters. They have 28 layer optical coating, AGC glass - rated for reduced reflection/refraction.

What does that really mean to us, as drone pilots? Aerial Photographers & Videographers? For me, it's the ability to shoot in challenging conditions. When I'm out there, the golden hour in full swing, sun is low, flares on my lens are beautiful opportunities. When I test out new filters, I want to head home with winning video and photo's. A great set of filters helps get the most of great conditions.

But that high sun at midday, so bright, the color is leached from the landscape, bleached from your subjects. Thus is when top quality filters are mandatory. That 180 rule for motion blur we have all been schooled on, but for controlling glare, those overwhelming reflections from water, buildings, vehicles and yes, even leaves on the trees, PL Filters give you control back.
