77mm Black Mist 1/4 and ND2-32 (1-5 Stop) Variable ND Lens Filter 2 in 1 with 28 Multi-Layer Coatings Nano-Xcel Series
SKU: KF01.1815
This thing works like magic. I honestly don't totally understand how it works, which is always fun. But it does indeed work. This ND filter can go from ND 2 all the way up to ND 32. This means you get a full 5 stops of ND, which can really come in handy if you (like me) shoot a lot outdoors in the daylight.
It also has a "black diffusion" effect that is at a 1/4 strength. This gives everything a touch of softness and diffuses the light nicely. This little addition makes the filter uber specific and might not be for everyone, especially if you're just looking for an ND filter. But I love the added touch of softness I get.
It comes with a beautiful leather carrying case, which will get more use than any other filter case I own. Mostly because this filter isn't the kind that will live on my lens 24/7 like a protective UV filter. I love knowing that the filter is safe in its leather case when it's not in use.

Very happy with this filter lens! It comes very well packaged and even comes with a nice quality leather storage case. Very nice touch. It fits on my camera with no hassle and stays put, so I’m not worried about it falling off easily. The filter itself is great! The diffusion is really strong and works well! It allows you to shoot longer exposures at a slower shutter speed in really bright lightening that you wouldn’t otherwise be able to shoot. It has an adjustable 1 to 5 stop reductions. Because it’s a 1/4 effect filter it also gives a somewhat soft diffusion to photos that looks great on portraits!

I tested out the 82mm version of the Black Diffusion filter with a Canon 24-70 2.8L lens. The filter fit properly and works smoothly with its well-designed adjustment lever. The filter is quite close to neutral in terms of color alteration, and A/B photos of a bright red car in the sun showed no color shifting at all. I often like HDR shots with the sun in the frame, and this is where the filter proves its worth. Some experimentation suggests that this will be wonderful for photos that include large oceanscapes or other bodies of water, particularly on a bright sunny day. The filter comes with a nice case and is easily cleaned with a microfiber cloth if you get a fingerprint on it.

This is a review of K&F Concept 62mm Black Diffusion 1/4 Effect & Variable ND2-ND32 ND Filter 2-in-1 for Camera Lens with 28 Multi-Layer Coatings (Nano-X Series)
I bought this to use with my Sony ZV-1 on which I have a Newer LS-18 Wide Angle/Macro conversion lens 0.75x. I was disappointed, but not surprised that there was very apparent vignetting at the corners of the photos. This is due to the wide angle lens. You can crop the photos in post production to eliminate the vignetting. Not ideal but that's what you have to do.
If you use this on a normal lens and aren't stacking additional filters, I'm quite sure you won't have an issue with vignetting.
The 62mm variable ND, 1/4 diffusion filter is great. The filter allows you to shoot longer exposures at slower shutter speeds in bright light conditions allowing you to get awesome shots that would otherwise be impossible to get without the filter. It adjusts to give you between 1 to 5 stops reduction. And since it's also a 1/4 effect diffusion filter, it gives a somewhat soft diffusion effect to the photo and is great to use for portraits.
This is very nice quality filter and priced less than other comparable filters.

For its price range, it more than meets my expectations.
In the dimmest light, it may slightly tint the colors, but that's to be expected with these filters, especially in this price range. However, it's completely usable at its dimmest settings, both in photo and video.
For video, if you want to be able to maintain the aperture setting based on frames per second (1/50 for 25FPS, for example), it's essential in natural light. I've always had it with my camera since I got it, and I really appreciate it.

Nothing to say, it's black mist and it respects a clean nd. Good enough range to cover a good sun and the dial is fluid without being flexible to avoid any change in case of movement.
