K&F Concept 77MM UV Filter & CPL Polarising Filter HD Anti-Reflection 28 Layer Multi-Coated Slim MRC Optical Filter (Nano-X Series)

This is an impressive two-filter kit. Common to both filters, they:
- Offer excellent transparency
- No discernible anomalies in the glass
- Excellent image quality
- No coloration
- The low reflectivity coatings offer easy cleaning and scratch resistance
- The ring and threads are well formed
- Sufficiently thin form-factor, excellent for most applications including UWA
- Nice anodized finish
- Satisfactory knurling to aid installation and removal
- Hard cases
- Lens caps, lanyards and microfiber cloths add value

Additionally, the polarizing filter rotates well and polarizes effectively. Excellent.

Misses?
- There are no labels on the filter cases. I'll make my own labels as I don't like to carry boxes.
- The filter cases are a bit thick as they are designed to hold both a filter and a mounted lens cap.

Nothing major but worth noting.

The K&F products I have had over the years are generally well designed with excellent attention paid to detail. This two-filter kit is no exception. Worth considering. Recommended accordingly.

My personal impression is that K&F has slowly become the market leader. I have complete confidence that I will get good quality here. The workmanship is flawless. (I'm only an amateur photographer though and can't give you any comparison values ​​for other filters.)

I actually only see potential for improvement in the packaging. The plastic boxes for the filters are unnecessarily large and always unlabeled, so that with a whole collection you have to get to it yourself if you want to know what's in it. It can be done better.

Being a professional photographer requires me to always improve the quality of the pictures and this UV filter is excellent not only to protect my lens but also is good at reducing reflections and glare allowing to and has the colors in the pictures.
For example, when it's too much sun it is very difficult to take interesting photos, however with this filter the sky in the picture looks nicer it allows for me to get amazing landscape photography.
This filter also is good to protect my lens from scratches and dust which is very useful considering that I am taking pictures mostly outside.
The actual filter is very easy to install and remove, requiring just to screw it on the lens and it stays securely in place and because the lenses are very light, it does not add any extra weight to the camera.
This is a good and efficient way to improve my photography even when I'm outside and it is sunny.

they always say that you get what you pay for and there's some truth to that. I would not buy an extremely cheap filter, but at the same time, buying the most expensive one is probably overkill unless you are a professional who is looking for a particular result. But for the casual consumer, or at least one who isn't paid to take pictures or video, going with a good consistent brand like K&F is ideal. High quality build, so you aren't worry about it torquing and getting funky when you take it on or off. Even better would be a magnetic one, but I am working up to that. The glass is more solid, resilient, and you can just tell that it is less fragile and clearer than the cheapest filters. Mainly, I use it for protection on my $1000 lenses, so why spare a few extra bucks and get something that distorts all of that high quality glass? I buy from K&F consistently, while still shopping other brands from time to time, but the prices on K&F are always very fair and the quality is consistently good.

kf congcept-a-like, the order was there within a day. When unpacking, there were no noticeable “chemical processing odors.”


The K&F Concept Nano X-series filter set comes in elegant packaging and practical storage boxes - that alone immediately impressed me!
The combination of UV and polarizing filters provides exactly what I need for safety for my photography and videography jobs. The 28 layers of nano coating ensure a good reduction of reflections and prevent any ghost images fairly well. As a result, the images have significantly higher clarity and contrast.

The polarizing filter does a really good job of eliminating polarized light and increasing color saturation. It's almost like having an ND lens with you, as the light is reduced by one level — perfect for high-contrast landscape shots.

The quality of the optical glass is top-notch. Thanks to grinding and polishing technology, the filters are ultra-high-resolution, and the multi-coating makes them resistant to mold, water, scratches and oil. I also find the robust CNC frame particularly practical, which minimizes stray light and is easy to assemble and disassemble thanks to the trapezoidal pattern.

The accessories are also great: 

The lens cap with the innovative non-resilient structure can be installed in seconds, and the cleaning cloths are securely vacuum packed and clean very thoroughly.

Overall, this filter set offers excellent performance at a fair price. It is a must for any photographer who values high-quality equipment. 

Highly recommended!

Price/performance is really great!

Let me start by saying that as a photography enthusiast, investing in the right gear is crucial, and the K&F Concept 82mm Circular Polarizing Filter & MC UV Protection Lens Filters Kit has been a game-changer for me. From the moment I slipped these filters onto my lens, I noticed an immediate improvement in the quality of my images.
The polarizing filter, in particular, has become my secret weapon for capturing breathtaking landscapes and eliminating unwanted glare. Whether I'm shooting a serene lake or a bustling cityscape, this filter allows me to dial in the perfect amount of polarization, enhancing the colors and contrast in a way that truly brings my shots to life. And let's not forget the UV filter, which acts as a trusty guardian, protecting my precious lens from the elements. While the kit is a bit pricier than some alternatives, the superior optical quality and multi-layer coatings make it a worthwhile investment for anyone serious about their craft.

Well packaged, and included everything I needed. It not only provided the polarizing filter lens, but also cover for the lens, and a strap for the lens cover. It fit perfectly on my Tamron e mount lens. Extremely easy to use, and with the cover already included I won't have to worry about the lens getting damaged. Absolutely love that it's waterproof so I won't have to worry about shooting with it during the rain. There's a huge difference in color, and saturation when the filter is used vs when it's not. Great value for the price.
