If you’re a Fujifilm X100 series enthusiast, this black diffusion mist filter is a great addition. It’s compatible with a range of models, from the X100 to the X100VI, ensuring you get that dreamy, cinematic look no matter which camera you use.

The filter is crafted from AGC optical glass. The 28 multi-layer coatings also help cut down on reflections for sure.

As you know, Mist filters are used to give a soft look and this does it really well. It works wonders on skin, smoothing out wrinkles and blemishes for a more flattering, glamorous look. The result is a beautiful, misty effect that adds a touch of magic to your photos.
And let’s not forget the magnetic front frame! This design makes it super easy to stack with other K&F CONCEPT 52mm magnetic filters, giving you even more creative options without any hassle. Plus, it doesn’t interfere with your original lens cap, so you can keep everything protected.

This black mist diffusion 1/4th filter completely blew me away! It adds such a great depth to my picutres. im super happy with this! This looks to great on my Fujifilm x100V, you can't even tell its there unless you really knew!

The K&F Black Mist filter performs just the same as my twice as expensive filters for my bigger DSLR. It softens sometimes harsh highlights indoors without degrading the overall image. That's what I look for in this type of filter. Great with portraits and video, and perhaps even useful for street. I've yet to try it for that.

K&F makes a wonderfully broad line of cost-effective camera gear, and this filter is yet another example of getting more than you pay for.

K&F Concept has become one of my go-to brands for quality gear at affordable prices: this filter met all my high expectations. It’s solidly build with well cut threads, which make for smooth attachment and detachment. They make a few variations of on the black mist diffusion filters, with (if I’ve done my research properly) 18 multi-coating layers on the less expensive end and 28 layers (as on this one) on the premium end.

While it’s certainly possible to experiment with home made diffusion filters—a couple classics being stretch panty hose over the lens or smear a light layer of petroleum jelly on a UV filter—I wanted to experiment with a commercial one. Two types one often sees mentioned are white mist and black mist. Based on comparative samples, I liked the look of the black mist variant more. They typically come in one of four strengths with the naming convention: 1/8 (weakest effect), 1/4, 1/2, and 1 (strongest effect)—interestingly, I’m given to understand that exactly how strong a 1/8, for example, is, depends on the manufacturer. Again, based on what I’ve seen of online samples, I thought either a 1/8 or 1/4 would be the most useful. Having now tried this one, at 1/4, I could see getting a 1/8 too, but rather doubt I’d ever use a 1/2.

Note: this works on other camera lenses too: directly for those that take 55mm filters and with an adapter ring otherwise. I know, because I tried it!

I got this Black Mist 1/4 Filter for my Fujifilm X100V and it's absolutely gorgeous.
It's well made and it feels solid. It's not an exact match to the X100V, but very close.
The filter is excellent and does a good job providing a diffused and softer image which isn't very strong and can be left on the lens also for protection.
I recommend.

I'd wager that if you're looking at these filters for your x100 camera it's probably because you, like me, enjoy the film sims and want the softer feel to the photos (you know you've seen the videos talking about these like I have), and look there are a TON of options out there. Cinebloom, black mist, white mist, haze, whatever. The list goes on.

At this point, I now have a 1/8 black mist, a glimmer glass and now the 1/4 black mist and here are my thoughts:

The 1/8 version is very, very subtle to the point that it's barely noticeable unless you're looking for it or you've got a specific situation. The glimmer is the same for me as the black mist in terms of subtlety (same strength). The 1/4 strength black mist (this K&F one) is the one that tends to be on my camera the most of the three, though.

The build quality is excellent, and it doesn't interfere with the focusing of the lens - IF you have a lens adapter. PLEASE NOTE that you will 100% need an adapter with these if you're putting them on the x100 line of cameras or you risk damaging your lens. If you've got the adapter, though, then no issue - it allows the lens to move fine and it focuses quickly.

The 1/4 mist provides just enough character for my personal taste without making every single light bloom too exaggerated or every crisp line look like it was smudged with vaseline. It softens the sharpness just enough to take the digital character down a notch for those times when you want to fully enjoy the film simulations, and if you've never actually used a mist filter for things like light blooms and softening light sources then you'll be happy to know that this one does it well.

These filters aren't something that I use all of the time, but for the times when I am after what they can provide they come in very handy, especially because it allows you (on your fuji cameras) to turn off the clarity setting and speed up your workflow when firing off shot after shot without delaying the processing power of the camera.

I've used K&F filters alongside my more professional, "premium" filters for years and have never had an issue with them and this one is yet another one that does great in that regard. Whether you want the 1/8, the 1/4 (this) or even the 1/2 or more I think you'll find this filter to be worth the affordable price.

This is a very decent black mist diffuser. I normally would try to stray away from anything that could degrade sharpness but i think the camera itself needs a little more for a little more "edge". The filter itself is very easy to put on and feels like its decent quality with it looking very much like the x100vi in terms of aesthetic. I like the photos and dreaminess of black mist and this one is just okay not too much in terms of dreaminess and retains a little too much sharpness for me but i think it still creates the look. Clarity wise its definitely pretty good and retains alot of details being a black mist filter i guess those 40mp make a huge difference.

The effect is subtle, but definitely takes the edge of digital photos and gives them more of a filmic look.
Fits perfectly on the X100v, but not sure why it is so big? Also, it does not have threads on the outside, so you cannot stack filters with this.

This is a great lens filter for the X100VI camera. no filter adapters needed. It will fit directly on to the X100VI thread. The material is very high quality, a very close match to the camera color and design. It can also take additional filters on the front end. But it only takes 52mm filters, not 49mm size. K&F also has its own lens hood that fits with this filter as well. Makes it a perfect system for the X100VI.

Fits, but kind of pricey for a filter that doesn't also have UV or CPL also. Makes photos look more like film-ish. Hopefully I can stack other filters. Also I wish it came in black for the all-black fx100. Honestly this is nice but not needed, just a nice luxury since there's built in settings
