K&F Concept 82mm Black Diffusion Mist 1/4 Effect & Variable ND2-400 (1-9 Stops) ND Lens Filter 2 in 1, Putter Adjust Multi-Function Filter for Camera Lens with 28 Multi-Coated (Nano-X Series)

Great piece of glass. No issues so far. Love that this combines a mist and nd into one filter. Comes in a nice leather case.

This filter was phenomenal! Love the case it came in and the cleaning cloth.Highly recommended this lens if you are wanting to add a little Cine look! I attached some photos of a recent Seattle Trip I took where I used this filter.

Pros:1) Retains image sharpness2) Warmer color cast (which I prefer)3) Higher contrast than Freewell4) Larger range ND range than Freewell5) Build quality better than Freewell6) Better carrying case than FreewellCons:1) Each ND stop does not have a hard stop or even a numeric indicator so you're not sure if you are on ND 8 or ND 16. This can be a con for some but for my use it is not a big deal as I primarily shoot video and use a monitor to gauge my exposure and just rotate the ND until exposure is correct.2) Filter does not have a hard stop when it reaches 400 ND and you can keep rotating it till you get the X pattern.I'm comparing this filter to Freewell ND mist version since that seems to be the most popular ND filter being used especially in the wedding videographer circles.In terms of overall build quality I want to say the K&F filter definitely feels a lot better. Even the overall packaging makes you feel like you bought a premium product. I really like the rubberized coating they use. It feels very premium and it has a good weight to it. The anodized orange indicator is nice and allows you to adjust the ND stop easily. The case that comes with K&F's filter is much more useable and compact compared to the bulky plastic cases that freewell gives. (There was a time thatfreewell's filters wouldn't even fit their case if you installed the magnetic cap which was a huge oversight on their part although I do wish K&F had a magnetic cap as well since those are the best IMO)I am primarily a video shooter and I was hoping that the filters would have similar color casts but unfortunately they don't. It's not hard to fix this in post but still would have been nice if they did match as I have multiple cameras. I do however prefer K&F's color cast as I tend to like warmer images. I also like the halation on this filter more than I do the freewell. If you look at the image where I put the two side by side the K&F is more contrasty and the light spread is kept where it should be and not across the entire image like how the freewell does it. This looks a lot more natural to my eyes. In terms of sharpness I could not see a distinct difference between the two. Both look excellent.Biggest gripe that I see other people having is the fact that there is no indicators on the filter aside from the first ND2 and ND400. The rest of the stops are indicated by dots. I don't know why manufacturers create an excellent product and then do these kinds of small short cuts. Although for me in real world use this probably wouldn't affect me, it did make testing the two different filters a pain. This is the reason why I have only included one comparison shot because I could only test the ND2 on both filters as that is the only two ranges that are clearly marked on both filters.At the end of the day in spite of some of it's shortcomings the filter does do an excellent job of what it is supposed to do. Cut light without messing with overall image sharpness or colors and give it that nice "cinematic" glow and I honestly think it does it better than Freewell. Thumbs up from me and will be using it at my next paid gig.

Good ND filter, no X distortion on any setting, and way cheaper than "high end" alternatives. Pic attached was taken on a blindingly sunny day and there's no post work done on it whatsoever.

Great filter and the variable adjustment is a huge easy button when dealing with different lighting conditions. Just spin the dial and get the the exposure value you need...super easy, never have to swap out a filter.

If you're like me, you can't get enough dark, misty, ethereal and foreboding atmospherics in your photos. Well, that's the look I'm going for when I use this black diffusion mist 1/4 filter from K&F Concept. The Variable ND2-400 filter comes along for the ride but the Black Diffusion Mist filter is clearly...err...'not so clearly'....star of the show.I already had the K&F Black Mist 1/8 filter, which adds more of a dreamy and slightly otherworldly effect to photos. I shoot a lot of photos at night in cities, and the 1/8 filter is perfect for that scenario. Even at night, cities are bright but if you're shooting without this type of ambient light the 1/4 filter is the club you want to pull out of your bag. In some ways, both filters create an effect that evokes analog cameras. One of my favorite subjects is Southern Nevada and you can get some really cool images with these filters. I've used the 1/8 for shots in Las Vegas (spoiler alert: lots of lights there) but I'm looking forward to using the 1/4 to shoot in the desert or some of the more remote towns between there and Reno.At one point, photographers would try all sorts of tricks to soften up their images. Rumor has it that 'Penthouse' publisher/photographer Bob Guccione would slather Vaseline on the lens to get the look--'The Gooch' thought he was a much better photographer than he really was but his obsession with soft focus imagery really differentiated his publication from the more lurid competition no matter how he went about getting the effect. Less messy photographers would go with black pantyhose over the lens.I don't consider myself a serious photographer--I'm primarily a writer that started taking photos and videos to accompany content. I'm trying to learn more about photography and at some point when I have more time I'd like to get more into the artistic side of images. For now, however, I'm pretty content getting interesting photos/videos with my Nikon Z-30. I've started messing with filters to try some different effects.As for these K&F filters, they're a perfect fit for my 50-250mm telephoto zoom lens. They apparently have little black particles inside the filter to get the black mist effect--in fact, you can see them if you look closely which you will because your first reaction is that it's dirty. I can't give you an expert analysis on the build quality, but the frame is anodized aluminum and that's a pretty burly metal. The glass has 28 layer multilevel coating and it comes with a nice storage case. I have enjoyed using my 1/8 K&F filter and I'm looking forward to putting the 1/4 through its paces. Highly recommended!

This filter is everything I could have ever wanted. Such a beautiful effect. I'm so happy.

Tested this the other day, and I can confirm that there are no X patterns. Just be mindful of how far you adjust it. The intent was to take some daytime landscape photos beside the lake, and the pics look great. There is some color cast, but it's nothing to complain about, and easily removable with your fav editor. The only negative, is that it can be hard to remove, so don't screw it on like a bottle cap. When it stops, STOP! Do not tighten, and you will have no issue getting it off. Like many filters, you will need to take it off in order to use your lens cap.

Cumple las espectativas. muy buen producto.la presentación tbn un 10
