The KF has nothing to be afraid from the Tiffen one.

Works great for the price and is a solid filter

The filter and case is top notch. The filter itself if you look at it closely has tons of little dots/specks on it. It has the effect of softening the photo a bit, adding more contrast. I'm not sure I love keeping it on my lens, for some landscape photos it's not as ideal (unless trying for a darker, more arty one).

No need for expensive Hollywood Blackmagic nor Tiffen filters. This is a very clean filter with zero color shifts that does the job like any other expensive diffusion filter at much lower price point.

Black Mist filters are designed to give a dreamy look to images and especially videos by creating a "glow effect" to the whole image. The hard edges of the image will be softened, but the contrast in dark areas will mostly be retained. For the best effect, you want to use this filter especially around light sources. A subtle glow will be added around the bright spots. In the box you will find the filter and a nifty carrying case which can also hold other filters of different sizes. This filter produces great photos and is comparable to many other filters that cost more than this one. The strength of the effect of this 1/8 varies depending on the scene, although it can be quite dramatic in some situations compared to other 1/4 filters. But with all that said and done, this particular strength is pretty much in the middle. It's never too much and it's never too little. Great filter.

I love that ! It gives my videos the movie look I was looking for.

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.

Similar to expensive pro mist type filters, this gives the look a more cinematic sheen to videos and photos as it adds a slight haze to the look of the image. The filter gives lights a hazy effect without affecting sharpness and it also smoothes skin tones. All in all a nice filter that fits the camera and protects it and is better to have than a cheap UV filter. The glass doesn't stick to oil or fingerprints, so you don't have to constantly wipe it.

I ordered the 55mm Black Soft Diffusion 1/8 effect filter to use with my Nikon D5600. I'm a beginner, but I enjoy the effects of this filter, especially in daylight. The effect is subtle but effective. There's a nice bloom and minimal color change. No loss in image quality was observed. Thread on the filter makes it easier to screw onto the lens of my camera. Well packaged. Useful filter to have a wide variety of settings at hand.

I really like the soft light it creates in videos. It is especially noticeable in "colored lights". Made everything more dreamy and cinematic, especially at night.
