A professional filter for special applications
There are filters that you simply screw on and then forget. And there are some where you notice from the very first look through the lens: Something is happening with the image. It was exactly like that when I held the new 77 mm Black Mist 1/4 from K&F Concept in my hand — another filter for my manual video lenses on Micro Four Thirds, on both the GH6 and Blackmagic Pocket 4K. I was able to test it through the Amazon Vine program. The price was 135.99 euros in August 2025.
As usual from the manufacturer: brass socket, strong thread, no wobbling. I already have a number of ND filters and chargers from K&F Concept, and the manufacturing quality has always been at a level where you don't have to think twice about whether it will last. Unscrewing and unscrewing is as smooth as butter, even if you have to change the setup quickly on the go.
Black Mist — and why 1/4 works differently
The Black Mist function is not a gimmick for me. It removes this sometimes merciless sharpness from digital cameras, reduces skin blemishes and gives highlights that subtle, cinematic glow. I already have the 1/8 model, which is much more subtle. The new 1/4 looks stronger — especially in night photography or videos with selective light sources, the glow is more visible. In daylight, very bright scenes can look almost too soft, so I asked myself once or twice if that wasn't too much of a good thing when it came to landscapes.
I was pleasantly surprised by the very low tendency to reflect. Even backlight situations where other filters produce unsightly ghost images remain clean here. At the same time, however, you notice that the stronger diffusion effect can easily blur fine structures in architectural photographs — i.e. use them more carefully for documentary work.
In direct comparison to the 1/8 model, the 1/4 looks livelier, almost bolder. He brings a bit more “drama” into the picture. When shooting in a small bar with dim lights, he immediately gave me the feeling that I needed to rework less in post-production. In brighter outdoor shots, the effect is more present, which is not always intended.
My personal review
A high-quality tool that noticeably changes images. For creative video and portrait work, the 1/4 Black Mist is a powerful option, while the 1/8 remains the more discreet choice. I'll probably keep them both in my backpack — depending on how bold I want the picture to look.
