Everything perfect

Outstanding product! Better processing quality than my Tiffen and no bad color cast.

This K&F black diffusion filter is a great kit. It reduces contrast, makes blacks slightly grayer, and provides a soft bloom around highlights. This 1/8 filter is the weakest, but it still makes a noticeable difference to the look of the images you take with it. . I was able to test it side by side with a Tiffen Black Pro Mist filter, and the results from each filter are extremely similar to the point where I don't really see a difference in the image, and I certainly couldn't say that the one or the other is better than the other. Both frames are made from aluminum alloy, and I think any aluminum frame can benefit from a little grease, even if it's just grease from the skin of your fingers that you rub on the nets. More expensive filters have brass frames which tend to be much smoother and don't stick. The K&F filter has approximately 1.25" deep machined grooves on each side of the filter, which provides excellent grip for your fingers when screwing/unscrewing the filter. One aspect in which K&F is the clear winner is that the K&F filter housing is far superior to the Tiffen housing; the Tiffen case is a square case in which the filter is loose on a piece of polystyrene, while the K&F case is superbly designed to hold the filter in place very securely thanks to a clever system of rubber grooves which can accommodate different sizes of filters. There is a filter thread at the front so you can stack another 77mm filter on top. Overall I find this to be an excellent quality filter that is roughly on par with the quality of Tiffen filters. It's a useful tool to have in a camera kit and well worth investing in.

I bought this filter to test it against the Tiffen brand Pro-Mist and it didn't disappoint. There is a video on YouTube comparing these two filters side by side and the K&F is definitely a competitor. The price is fair which I liked, it also came in a nice container. Don't pay too much for the tiffen in my opinion.

I have both a tiffen vari ND and this one. And I like this one even better! My tiff filter has a slight bluish tint and it doesn't even turn too far. I also like that it has a hard stop and therefore doesn't have any x patterns. Quite the opposite of meeting.

I have the Olympus OM-D E-M1 Mark II which is a Micro 4/3's camera. As such, the lenses are tiny with less glass to cover, making the price of these filters extremely low. So I bought both this K&F Concept 58mm Black Soft Filter 1/4 and the infamous Black Pro-Mist 1/4 Filter. This is all subjective, but I prefer the look of the Tiffen black pro mist more. The K&F is a bit too bloomy, and the image loses a lot of contrast. That makes the K&F less versatile. Meanwhile, the Tiffen is more balanced, with less bloom and higher contrast. Making it perfectly acceptable for everyday use.Given the low price of this K&F filter, I'll still keep it. But, If I had to choose one, it would undoubtedly be the Tiffen Black Pro Mist filter.

Impressed with the quality of the filters and presentation. Very well made compared to other filter sets by tiffen and others, I didn’t give it 5 stars until I use it more. So far so good.

In addition, the k&f filter can filter out almost 1 1/2 stops more light than the tiffen, without a vignette.
If I hadn't already bought the Tiffen I wouldn't have it in my camera bag anymore. So he lies around and is no longer used.
