Fuji X100 Lens Black Mist 1/4 Filter, Multi Coated HD Optical Glass Scratch-resistant Compatible with Fuji X100, X100F, X100S, X100T, X100V, X100VI Nano-Xcel Series (Black)

The silver on the outer ring isn't exactly the same color, but it's hard to notice from afar. Other than that it's a really solid filter for the X100VI and really adds to the aesthetics. I like how it still fits the lens cover.

As a street photographer I love to shoot film, but it's a costly endeavor and my vintage cameras are not weather sealed, so I shoot mostly digital with either an in-camera film simulation or a film-like preset applied in post.

One of the film qualities that is difficult to emulate with a digital camera is exposure latitude in the highlights; digital easily clips in the highlights, but even when protecting the highlights they look somewhat harsh. Also, digital images in general are sharper than analog, and a black mist diffusion filter is one way to soften both the overall image and even out the highlights so it feels more like film.

This diffusion filter does an admirable job of creating just such an effect, without being overbearing. When shooting normal subjects in daylight it is almost unnoticeable, providing a very sutble softening effect. And as the sample photos show, when shooting into the sky, highlights and even flares tend to spread out and lighten the affected portion of the image, just like they do on film. Of course it's not exact same effect as analog, but it does add to the overall mood.

One thing I did not test this filter on was night-time light sources. Once I get around to that I will update this review, but I generally prefer less powerful diffusion for that use case.

For the price, I think this K&F filter is an excellent deal. K&F image quality is always quite good, and I was not able to detect any anomalies even at high magnification. One thing to keep in mind is that it does not have a front thread to take additional filters; however it does accept K&F brand magnetic filters, which is actually pretty cool.

Filter for x100
It basically transforms direct light into a mystical airy glove, a sort of fairy emanation
I did a quick test with direct light: where you see the spokes there is no filter, where you see the ball of homogeneous light instead is with the filter mounted.
Two notes on the object itself: color ok with the silver model.
What is strange is that one side has a 49 female thread, in practice it screws on the x100vi and sisters. The other side of the filter however has a 52 male thread!!! In practice you cannot mount other filters above or below it, other than the K&F magnetic system.

Great inexpensive diffusion filter for Fuji cameras, but also will work on any lens with 55mm diameter. On Fuji it will sit naturally and you can screw in 52mm filters on top or drop in magnet filters from K&F. The pictures and the diffusion effect is great. I didn't notice any color cast or flare or other artefacts. The filter does what it's designed to be. It creates glowing effect around the light source and also the softens the areas were the light is. It's great for portrait works where you want to have that cinematic look, also for street photography especially in night. Great quality product from K&F and cost effective compering to other brends.

This is a diffusion filter that adds just a subtle amount of haze to you're shots. It also exhibits a slight grey tint. I would approximate 5%. This product is compatible with the following cameras Fujifilm X100/X100F/X100S/X100T/X100V/X100VI (Nano-X Series).

The whole premise of this filter is to add subtle haze and bloom to film and video. This helps to soften light and overall skin. This helps in reducing wrinkles fine lines and pores. Adding a somewhat dream like effect. There are many grades ( percentage ) of haze you can add with various other filters in this lineup. From subtle such as this one to vary bloomed and hazy.

I have had the pleasure of reviewing K&H products in the past and they've always shown great attention to detail and superb craftsmanship. Their lens glass has always been superb with edge to edge sharpness and good optic properties.

Things to consider:
As you can see adding additional glass may result in reflections and extra light flares. This is common and is part of the trade off when using certain types of lens add-ons.

Final thoughts:
This is a good tool to have in you're kit. On those special occasions where you need extra mood. Perfect for weddings, child photography, dream sequences in film and many more concepts. With great build quality and a well designed carrying case. This product might be what you've been looking for.

Works perfectly without being too over powerful. Love the look that this filter creates.

This has pretty much lived on my silver X100VI since I received it. Among the positives is that it provides weather sealing for the camera, the color is a close enough match to the silver trim of my X, and I don't see any sketchy vignetting in the corners. Another product you can trust from KF Concept. Recommended

The K&F Concept Black Mist Diffusion 1/4 Filter is an excellent choice if you're looking to add a subtle cinematic glow to your images. I use it with my Fujifilm X100V, and it delivers that soft, ethereal look without overly compromising sharpness. The filter does a great job of reducing harsh contrasts and adding a bit of mood to portraits and landscapes. The build quality is solid, and the silver frame looks sleek. It also doesn’t interfere with autofocus, which is a plus for street photography. Overall, it's a fantastic addition if you're into that vintage or dreamy vibe. Would recommend if you want to elevate your shots!

Great highlight bloom without introducing weird colors. Recommend.

K&F Concepts is one of my favorite lens protection/filter brands out there. When they began releasing direct-fit filters for the X100 series, I had to get it. This filter replaces the Tiffen-brand black mist filter that I had adapted to fit the X100VI using a series of step down filter rings and an adapter for the X100VI itself. It added a substantial amount of length to the end of the camera and it definitely did not look aesthetically pleasing. This K&F filter changes that. All you have to do is remove the thread protector from the lens and screw this on. It even looks OEM with the silver ring it came with. It's not a perfect match with the X100VI's silver, but it's close enough. As for the diffusion performance, I could not tell a difference between the Tiffen brand 1/4 mist filter and this one. They looked identical to me in my testing. Great filter!
