This glass filter fits well. The quality is superb. It comes with a case as well. Perfect diffusion filter for my 90 mm sony lens.

Click to play video Let's start at the beginning. What does a "blur filter" do? It gives lights a "blur effect." In other words, the lights look a bit foggy. This can create a really cool look in film productions, but it's also really useful for photos, such as portraits. For example, a string of lights in the background of the model or something similar. Autofocus works perfectly with the Sony A7 Mark 2 and the kit lens. What I find absolutely brilliant is the "packaging," or rather, the place where the filter is stored. Nothing wobbles! It's rock solid and can even be used for other filter sizes. Oh, and despite the filter, the lens hood and lens cap fit without any problems. Top-notch workmanship, as always! No plastic ;-)

This K&F Black Diffusion filter is an excellent piece of kit. It reduces contrast, making the blacks slightly greyer, and provides a soft bloom around the highlights. There are four strengths of filter available; from weakest to strongest, they are 1/8, 1/4, 1/2, and 1. This 1/8 filter is the weakest but it still makes a noticeable difference to the look of the images that you shoot with it.

I was able to test this side-by-side with a Tiffen Black Pro Mist filter, and the results of each filter are extremely similar to the point where I can't really see any difference in the image, and I certainly couldn't say that either one is better than the other. Both frames are made of an aluminum alloy, and I feel that any aluminum frame can benefit from a little grease, even if it's just grease from the skin of your fingers that you rub over the threads. More expensive filters have brass frames which tend to be a lot smoother and don't stick. The K&F filter has about 1.25" of deep machined grooves on each side of the filter, which provide excellent grip for your fingers to hold when screwing/unscrewing the filter.

One aspect in which K&F is the clear winner is that the K&F filter case is far superior to the Tiffen case; the Tiffen case is a square case in which the filter sits loose on a piece of styrofoam, whereas the K&F case is superbly designed to hold the filter very securely in place with a clever system of rubber grooves that can accommodate different filter sizes.

This does have a filter thread on the front so you can stack another 77mm filter on top of it.

Overall I find this to be an excellent quality filter that is pretty much on par with the quality of Tiffen filters. It's a useful tool to have in a camera kit and is worth investing in.

Perfect for portraits.
Try it.

I'll start by saying that this filter will stay on my Canon 24-70 forever and that I'm satisfied and amazed by the effect it gives to my photographs. The filter comes in a hard case that already differentiates it from low-end filters: it is comfortable to use and has a non-slip part with different notches for different filter sizes. The construction is excellent and you can immediately see from the layer applied to the surface that it is a professional tool. If you are a photography geek like me, to give an effect similar to diffusion/glow, you will have already tried things like Vaseline on the lens, stockings pulled over a filter or various films. This filter is completely different. It has a subtle effect and does NOT degrade the image. The edges remain sharp while the colors seem to fade slightly within the photo, restoring the quality that you had with the use of film: truly pleasant! I bought it for photography in broad daylight, but certainly one of its best applications is with lights at night where you can appreciate this diffusion of color and brightness more. Although it is an overused term, this filter gives a touch of organicity to digital photographic paste. I would like to point out that it does not have a blatantly and vulgarly diffuse effect, but visible without attracting attention. Highly recommended for videos too!

similar to the expensive pro mist type filters, this gives the look a more cinematic glow to videos and photos as it adds a slight haze to the look of the picture. The 1/8 is lighter than the 1/4 filter size and always get the 82mm thread size as you can get step up rings to fit the filter. The filter gives the lights a fog like effect without affecting the sharpness and it smoothes out skin tones as well. Overall nice filter that fits the camera and protects it and is best to have than using a cheap UV filter. The glass doesn't adhere oil or fingerprints so you don't need to constantly wipe it down as well.

had my doubts before purchasing this 82mm Black Mist filter, as I mostly shoot landscapes and thought they were only used for portraits or street photography. I wasn't entirely sure what I could achieve, but I was pleasantly surprised. A filter that creates a special atmosphere, adding a kind of mist around points of light. In the photos, you can see the effect it creates. I find it very interesting, and I think it can give photos a special touch in many situations. The filter is a threaded type and comes in its own plastic case, which also fits different filter sizes, from 43mm to 82mm. The rim is metallic, and the filter is glass. Right now, all I can think of are landscape applications. I think it's a very interesting option that I'm really enjoying. I'm leaving you with some photos and a video so you can understand the effect achieved using this filter.

Excelente, muy buena calidad de producto.

I am pretty happy with the results. It works best in strong harsh sun light.

Now it is always on my cam!
