So I think a lot of people involved in video products are very familiar with the Tiffen Black Pro Mist filters. This is K&F's version of this filter. I'll elaborate on what I think about the filter, but you can judge for yourself in one of the pictures in this review, where I show you the same image; the first without filter then with the filter.

One of the results you get with such a filter is the blooming of the highlights. This filter does that pretty well. Comparing the bloom to the Tiffen line, I'd say it's between Tiffen's 1/2 and 1/4 strength, being closer to 1/4. The highlight fall from IMO was strong but natural. Remember that the light in the image fills the frame, so you're seeing this particular effect of this filter at its most extreme. You won't see as much flowering in a more natural environment. Take a look at the camera highlights. For me, the K&F filter had a big impact on highlight roll-off, which was very smooth.

The other effect you get with a black fog filter is slightly reduced contrast and slightly softening of the shadows. For me, I thought this filter did that pretty well. If you look at the texture on the camera handle in the image, you can see how that texture is just softened. Imagine shooting a person and you can imagine how much you could smooth the skin.

It also comes in a nice little screw together plastic case. Inside the case is this little rubber stopper that keeps the filter from sliding around in the case. I love the attention to detail here.

Compared to the Tiffen version of this lens at the size I got, which was 82mm, the K&F Black Mist is about $40 cheaper. I think you get good value for your money here. Can't wait to try this filter on some upcoming shoots.

I think K&F is moving into higher end filters and if this filter is an example of the kind of quality it can produce I can't wait to see what filter they release next.

Great product! Better build quality than my Tiffen, and no nasty color cast.

These is my 2nd variable ND from K&F. The quality it's good as Tiffen and others manufacturers. Instead of have a lot of ND of different sizes it's better have a variable ND for my photography work and save same money.

The only CONS it's the protective case that came with the ND. It's nice but too big.

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 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.

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.

Excellent product! Better workmanship than my Tiffen and no nasty color cast.
