82mm Black Mist 1/4 + CPL Filter Set, Dreamy Cinematic Effect Mist CPL Polarising Filter 18 Multi-Layer Coatings Nano-Klear Series

K&F filters have quickly evolved from an insider tip to an established player in the camera accessories market.
This is no different in this case: The set of mist filters and polarizing filters is well-made, easy to screw on and off, and delivers stable results without compromising image quality.
The package also includes cleaning cloths and the two screw-on filters in a plastic case.

First, the packaging is premium and included three (not just two) micro fiber cloths. The cloths are nice and soft, and since it's made by a camera lens filter company, I'm confident I'm not scratching any of my electronics' lenses/screens.

Now for the filters, they offer a subtle yet nice touch to alter the video/photos you take with your cameras. I've attached one (and both when stacked!) to a Sigma F2.8 18-50mm e-mount lens which fits perfectly without crossthreading or adding too much bulk.

Overall I'm very satisfied and can't wait for a sale to pick up some to add to a collection!

This review is for the K&F Diffusion and Polarizing Filters. I ordered the 67mm size for my Tamron 28-200 lens.

These filters are great. The build quality is strong and they are easy to thread onto the lens. They function as expected and the quality is what I've come to expect from K&F.

Great for photographers!

I have always liked K&F quality for the money. I have about a zillion of these orange packages of cloths now. This is a great combo if you just want a basic kit. I love the look of pics with the diffusion. Especially at night. During the day the effect is less pronounced, it still enhances backlight and side light rays. I didn't notice any discernable color shift. I have had a few lens filters of various prices and quality and the main difference in most of them is how they are coated to resist marks, light scratches, and prints. These may not have as many coatings as more expensive ones, but I found them to thread on smoothly, do what they were meant to, and wipe off cleanly. A water bead rolls right off. I would recommend this kit!

I’ve used polarizing filters before and often found them to be bulky and cumbersome. Not so with these 58mm filters from K&F. The polarizer rings are a svelte 7.1mm.; the black diffusion filter, 5.8mm. The former weighs .6 ounces, the latter .5 ounces. Both are circular and have sufficient thread to securely mount to my UV filter, and once in place, didn’t interfere with my lens cap or lens hood. Shooting mostly in partly cloudy daylight, the polarizer rotated smoothly and produced the expected results of reduced reflections and enhanced color saturation. I’ve not used a black diffusion filter before and received best results with contrasty indoor lighting. At 1/4, the filter diffusion effect level rating is not the highest. The effect is pleasing, but subtle. Included with the lenses are two microfiber cleaning cloths and a quality carrying case.

This kit comes with 2 lens filter and 3 sealed lens cleaning cloths. The lens filter includes a black diffusion 1/4 and a Circular Polarizer (CPL). I mostly take wildlife pictures and lately I wanted to experiment with other types of photography. I got these 2 filters to explorer and learn and to see what I can achieve. The semi-low cost makes it economical to experiment without making me feel I wasted a lot of money.

I already have UV filters from K&F and these filters feel well made just like those UV filters. I do wish K&F would of provided 2 case instead of sharing the 1 case but it keeps the cost down. The CPL filter turns buttery smooth! I only did a few test shots and I haven't notice any imperfections in my photos with these filters on. After owning several K&F products, I feel they make great products at a great value.

As with other K&F filters, these are of spectacular value. The machining is excellent, and I like the design with large knurls to help screw them onto the lens.
The optical quality is excellent. I often use this combination when shooting outdoor events like concerts, exhibitions, and parties. Adding these filters gives the shots a "finished" look that stands out compared to mobile phone shots of the same subject. The 1/4 black diffusion is very subtle; in most cases, it barely registers. It adds a cinematic look to the tone. The black diffusion really comes alive when there are specular highlights like backlit hair; then, the diffusion causes a subtle glow.

The CPL filter does a good job of darkening the sky, reducing reflection and glare. It needs to be rotated to find the effect (The filter is designed to rotate without unscrewing). It's important to test the filter in the environment; in rare cases, it will cause unwanted effects like vignetting or the sky looking unnaturally dark but lighter at the horizon. It all depends on the lens and sun position.. But overall, this combination is killer for day exteriors featuring people.

I ordered this 46mm 1/4 diffusion filter + polarizing filter set from brand K&F Concept for my 50mm f/2.0 Fujifilm lens, and while the term "Black" diffusion is usually an ideal created by the more premium filter brands like Tiffen with their "Black Pro Mist" ideal, I think it's a generic term that can be used by any brand, as this filter creates an identical soft focus effect.

I have no issues with this filter set at all, in fact it was ordered as a replacement for such a more "premium" classic filter that broke, and the addition of a quality CPL filter as well for the same or lesser fee, is a great value to me. They both match quality as far as I am concerned, in terms of the effect each produces, and also the quality of the aluminum casing, and the glass itself. I honestly see no difference. I have always loved this diffusion effect, as it allows me to create a more "filmic" look to my images.

Product is relatively equal in terms of quality average over other brand names, K&F Concept really knows the needs of photographers overall. Even comes with cleaning pads. 5 stars.

A brand that never disappoints, K&F Concept! This product represents two excellent filters that can be perfectly combined with each other, they are able to eliminate the reflection of light (CPL) and give the shot a softer color and brighter colors (Black Mist). These filters are of excellent workmanship, they attach perfectly to the lens with a very stable grip. They are also resistant: I accidentally dropped them a couple of times and they did not break. They also come with three disposable cloths for cleaning. I was really satisfied!

I decided to try this K&F Concept filter kit because I needed both a 1/4" Black-Mist filter and a CPL to enhance my shots, especially outdoors and under artificial lighting. After several testing sessions, I can say that the product's quality lives up to expectations.

Quality of Finish
The first thing that stands out when holding these filters is the quality of construction. The aluminum frame is lightweight yet sturdy, with precise threading that makes it easy to install and remove. Additionally, the glass has a nano-coating that repels fingerprints and dirt, which is always appreciated in everyday use.

Effect of the 1/4" Black-Mist Filter
This filter is excellent for softening highlights and creating a cinematic effect without losing too much detail. It subtly reduces contrast and helps the highlights diffuse naturally, without creating an exaggerated or artificial effect. I've used it in night photography and in harsh-light portraits, and in both cases it gives a more professional look.

CPL Filter: Improved Reflections and Saturation
The polarizing filter does its job without adding unwanted color casts. Reflection control on surfaces like glass and water is noticeable, and the increase in color saturation is perceptible without being excessive. It works especially well in landscapes, where it achieves more defined skies and more vibrant colors.

Packaging and Accessories
The kit comes in a well-protected case with three cleaning cloths included, which is a nice touch for keeping the filters in perfect condition. The overall packaging conveys quality and attention to detail, which is always appreciated.

Conclusion
This K&F Concept filter kit is an excellent option for those looking for versatility without compromising quality. The 1/4 Black-Mist achieves an attractive cinematic effect, while the CPL is ideal for eliminating reflections and improving saturation. The construction is solid, the packaging is high-quality, and the results are very good. Without a doubt, a great addition to any photography kit.
