K F CONCEPT 77mm Ultra-Low Reflectivity MCUV Lens Protection Filter 28 Multi-Layer Coatings Ultra-Slim HD Waterproof Scratch Resistant

As a photographer, the first thing I do with a new lens is fit it with a quality UV filter. After using the K&F CONCEPT 67mm Ultra-Low Reflectivity MCUV filter, I can confidently say it delivers the highest level of protection with zero compromise on image quality—which is exactly what you want from a clear filter. ​Optical Purity and Clarity ​The "Ultra-Low Reflectivity" technology isn't just marketing—it's genuine. Shooting directly into harsh light or around bright, specular highlights is typically when cheaper filters introduce distracting ghosting and flare. With this K&F MCUV filter, my images remain crystal clear. The multi-coating (MC) effectively minimizes reflections between the lens elements and the filter glass, making its presence virtually invisible to the final image. I’ve noticed absolutely no reduction in sharpness or color fidelity; the images are just as punchy and detailed as if the filter wasn't there. ​Superior Build Quality ​The frame is a beautifully engineered slim design, which is crucial, especially when using wide-angle lenses. I haven't experienced any of the notorious corner darkening or vignetting that thicker filters cause. The threading is buttery smooth and seats perfectly onto my lens barrel every time, making it quick and secure to attach or remove. ​Peace of Mind Protection ​Ultimately, a protection filter's main job is to guard your expensive front element. This filter gives me the peace of mind to shoot in dusty, sandy, or wet environments without worry. It shields the lens from scratches, fingerprints, and accidental bumps. Plus, the multi-coating makes it far easier to clean off smudges compared to uncoated glass. ​If you're looking for professional-grade protection that won't degrade your optics, the K&F CONCEPT Ultra-Low Reflectivity MCUV filter is an absolute winner and a mandatory accessory for your kit.

Amazing piece of glass. I purchased this 67mm K&F filter for my Tamron 17-70 that pairs with a Sony A6400, and it takes gorgeous photo's. I know people say "Why put another piece of glass in front of your perfect lens?" but that is far from the truth. This filter serves many purposes and well worth its price compared to other high end filters. Not only does it act as a protection from dust, scratches, and damage to the main lens, it also acts as a UV filter that gets rid of blue tones that reflects into the camera sensor. When buying a UV lens filter it's important to find a high percentage light transmission glass, 98% or better, allowing highest amount of light to pass through. This K&F Nano X Ultra Low is rated at 99.8% transmission! Its also rated at 0.1% reflectivity anti-glaring with its 28 layers of coating. The coating also helps making it more water and scratch resistant, and easier to clean. I was able to shoot some photo's of snow fall and really helped knowing I wasn't scratching my mains lens every time I had to wipe off the wet snow. Image quality also stayed crisp and clear with no impact on quality or shutter speed. Even on bright sunny days, I had no issues with unwanted glare and picture colors stayed true to what was represented. This UV Lens is truly amazing. It's thin aluminum profile helps keep it thin, sturdy, and light. The high quality glass, with its 28 layer coating, offers protection that doesn't effect image if not better. For 32 dollars, K&F has earned my trust and given peace of mind in protection of my $700 lens. Recommend and will buy from again. I've actually now purchased its ND+CPL filter, and another UV filter (a grade below this one with 24 layer coating). Stay protected and capturing one moment at a time! Read more

At this point, I have 6 different filters from K & F. I have the same exact version of the UV filter for 67mm and 72mm. The 82mm version affects the image differently in my opinion. Specifically, I used this with Sigma 24-70 and there’s a noticeable difference in quality - something I that is not evident from the 72mm and 67mm versions. Still give it 4 stars as most of the other products I tried from K&F are well made - CPL true color, UV MRC, 1/8 BDC. They should look into what’s with the 82mm UV. Read more

I bought this lens filter to protect the lens on my Fujifilm X100VI, and it’s been exactly what I needed.

The build quality is solid, and it doesn’t add any noticeable bulk or weight to the camera. If you’re looking for simple, effective protection, this is a no-brainer. Read more
