I love the look this filter gives my video, I can't live without it!

I am happy to have purchased this K&F Concept Filter Black Diffusion Filter 1/4 82mm the effect in the videos is very pleasant and cinematic.

Really nice quality filter, comparable to more expensive brands. Has that black pro mist look. Softens things and gives lights a bit of glow. The he 1/4 does enough but id be curious to play with the stronger versions too.

I bought this 72MM filter supplied with the Sigma 18-35 and it is now indispensable for my video productions. It gives an analog effect that makes the images softer, the action around the lights is perfect and not annoying, moreover the production quality is high. It has a double thread to be able to overlap multiple filters and is equipped with a rigid case, for safe transport, with an anti-slip triangle inside (therefore usable with different filter sizes). At the current price it is a must.

So I think a lot of folks involved in video product are very familiar with the Tiffen Black Pro Mist filters. This is K&F's version of that filter. I will go into what I think about the filter but you can also judge for yourself in one of the pictures in this review where I show you the same image; the first without the filter then with the filter.

One of the results you get with a filter of this type is blooming of the highlights. This filter does quite a good job of that. Comparing the bloom to the Tiffen line I would say it falls between Tiffen's 1/2 and 1/4 strength with it being closer to the 1/4. The highlight fall of was strong but natural in my opinion. Keep in mind the light in the image fills the frame so you are seeing this particular effect of this filter at it's most extreme. You won't see that much blooming in a more natural setting. Take a look at the highlights on the camera. To me the K&F filter had a great effect on the highlight roll off which was very smooth.

The other effect you get with a black mist filter is the slightly reduced contrast and the slight softening of the shadows. To me I thought this filter did this quite well. If you look at the texture on the handle of the camera in the image you can see how it's just sort of softened that texture. Imagine shooting a person and you can imagine how much you would be able to smooth out the skin.

It also comes in a nice little screw together plastic case. Inside the case are these little rubber stopper than prevent the filter from sliding around in the case. I love the attention to detail here.

So 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 are getting a lot of value for your money here. I can't wait to try out this filter on some upcoming shoots.

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

I had my doubts before I bought this black mist 82mm filter, because I mainly shoot landscapes and I thought that they were only used for portrait or street photography. I wasn't sure what I could get out of it and I was pleasantly surprised.

A filter that creates a special atmosphere, adding a kind of haze around points of light. In the photos you can see the effect that it generates, I find it very interesting and I think that in many situations it can give a special touch to the photos.

The filter is a screw-on type, it comes in a plastic box, which also fits different sizes of filters, from 43mm to 82mm. The rim is made of metal and the filter is made of glass.

Right now I can only come up with ideas to investigate landscape applications, it seems to me a very interesting option that I am enjoying a lot.

I really like the soft light that it produce in videos. It's especially noticeable in "color lights". Made everything more dreamy and cinematic, especially at night.

Great filter with nice features at a decent price. About 3mm thick. Screws on fine. Hard case.

In the pictures, the first image is with the filter on, the second one is without the filter. Shot with the Nikon 50mm f/1.4 lens at f/1.8. The main difference is in the highlights area. Note how there is loss of contrast and a gentle glow effect around the candle lights and around the stronger highlights. Also, there is a very subtle, dream-like haze in the image, the image sort of feels a little bit warmer.

I can definitely see how this filter will have its place in my camera bag.

Quality-wise, the filter is very nicely made. The storage case is hugely oversized. Looks like the same case size is used for all filter sizes. This is suboptimal for the consumer, since there is no reason why I need to find space for the huge case for a small filter.

The retail box is presentable, and projects quality. The whole package would make a nice gift.

I am usually against UV/haze filters as I am concerned about their effect on image quality. However, I plan to use my Sigma 150-600 DG DN Sport (Sony E-Mount) in pretty harsh conditions such as coastal bird photography, surf photography, and sports. So, I caved and purchased this filter to provide protection for the lens front element.
However, given that this K&F filter would probably be considered "mid-tier" in terms of price, I wanted to test if it in fact had any effect on image quality. The attached image of a $20 dollar bill was taken under the same exact circumstances - 600mm at ISO 100, tripod with OS off. As you can see from the screenshot taken in the compare view of my photo editing software, the image on the right (with filter) is clearly sharper with better contrast.
I'm shocked! I had fully expected to remove the filter when I wanted a better image. Now I can leave it on 100% of the time, and easily wipe off any splashes or dust without worrying about scratching the front element. Strong recommend!
