It’s great to have polarized and ND in the same filter, tint it’s a little yellow but the glass quality it’s great, the coating rejects liquids very efficiently even test it filming a car video with rain and the quality of the image was really good

I’ve been wanting to buy an VND filter for a while but with so many brands…. I couldn’t decide. I finally made the jump with the K&F thanks to the low price point. I thought, “ant this price I’m not losing annything. Besides I can return it if I don’t like it. let me tell you that I couldn’t be happier. The built in Polarizer gives beautiful colors as you can see in my shots above. It hardly ever leaves my lens. I bought it for my RF 50mm f1.8 and now Im going to get one for all of my lenses.

This product is the best value ND filter out there.
-Very little color shift, easy to correct in post or by white balancing camera
-No X or Vignetting when shooting 24mm. It does apparently vignette at lower focal lengths, but I had no issues
-No visible image quality drop that I can see
-Polarizer words great, a must have for increasing saturation and controlling reflections. This was the reason I got this particular filter; the added polarizer was necessary to deepen colors and reduce glare.
-Plenty of stops of ND to shoot video in daylight with f/2.8 in more shadowy areas and f/5.6 everywhere else (shutter 180º and ISO 200).
I cannot recommend this product enough, it works great and I take it with me whenever I shoot now.

This filter turned out to be better than I expected.The construction is very solid and the rings turn smoothly.I am very pleased with the results it gives but I would advice caution when using it on ultra wide lenses.All in all another winner from K&F!

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

Definitely worth the price. The highlight of the filter is the manual adjustment for the amount of light that comes in.

Very nice to be able to adjust both the ND and CPL from one filter. You do need to be careful though as adjusting the ND Filter can also accidentally turn the filter, unintentionally adjusting the CPL.
Works great on my Panasonic GH6!

The K&F Concept 72mm Variable Fader ND Filter and CPL Circular Polarizing Filter is a must-have for any photographer or videographer. Convenience of 2 filters in 1. Works well, easy to use, and can be used in many shooting situations. Two Thumbs Up.

I wanted to slow down my shutter speeds to smooth out lake water etc. I assumed (incorrectly) that the fader and the polarizer portions wouldn't affect each other, but that's incorrect.
Once one sets the ND fader to its most dense (32) no matter how you turn the outside ring, (which affects the polarizer,) you will have dark areas somewhere in the frame. This only goes away around 30mm, which is how most polarizers work, and I was aware of. I had assumed I could just have it "not working" while I used the ND properties.
So if you want to use this, it is pretty much useless below 30mm as you'll get dark spots. Note the top two corners of my example plus the lower left corner. If I turn the polarizer (front ring) those spots just move to other spots. I should have bought a set of ND screw-on filters instead for my purposes. Unfortunately, there is no documentation or information anywhere on K&F site or reviews that would have alerted me to this drawback.
