I used it with a Fujifilm x-t4 18mm f1.4 and all I can say is wow. Didn't expect such results.

I have always been a fan of K&F after buying their tripod, so I was pretty sure about the quality of ND.This is 1of 3 NDs I have purchased for my crew, and I should say this is amazing.I would start with the build quality, and it's pretty sturdy, the casing is aluminum and lightweight.Coming to the colors, I didn't see any difference in colors with ND on at Min and ND off. Also, the cutting down of light from ND 2 to ND 32 is so accurate for an ND(measured with exposure meter).

During the window test, when we set ND to the maximum value, I didn't notice X.

My choice fell on Polar Pro or K&F. Well, now I know the answer! This filter exceeds my expectations! The high-quality processing is PRO. You'll see when you run this filter on your lens, after all I don't need two separate filters on top of each other. From now on, I've stopped buying cheap filters, especially if you have a loan that costs over $1000. K&F did a great job here and for the price it's fantastic!

Works great, has smooth action, and kills two birds with one stone by being able to spin and kill reflections. The only complaint is incompatibility with many lens hoods, but well, it's better to reduce the diffraction and hit your target than eliminate the diffraction and have to jump through hoops to get a decent shot.

Very easy to use and produces high quality images. Being able to adjust exposure without removing and adding filters makes shooting so much faster. Image quality is great.

The filter is supplied in a plastic carrying case with high quality foam for protection. The filter sits firmly in the housing, so you can be sure that it will not move after storage or be damaged during transport.
The filter itself feels of good build quality, with the metal frame holding the glass in place. I like the lever to adjust the stops, the action is smooth and doesn't move on its own. I would have preferred that K&F included a lens cap just in case I wanted to leave the filter on the camera.

Pros: Great packaging, clean glass, no color shifts.
saves a lot of time on run and gun shots. especially with gimbals
Cons: requires practice to turn it with one hand. Just remember to turn off your gimbal motors before rotating the filter or you may damage your gimbal motors.

I love that this is a combination of variable ND and polarizing filter. It makes setting up my shot so much easier without trying to put two different filters on. In addition, this filter feels and looks really solid. Another important thing is that this filter doesn't have that pesky "X" that some others have. I would recommend this and I think it would be great for anyone who wants a decent ND and polarizing filter without spending hundreds of dollars.
