The K&F Concept 52mm MC UV lens protection filter has no image degradation and fits perfectly on my Canon lens. It comes well protected with a lens cleaning cloth that can clip the lens cap. It's great to finally have dust, scratch and UV protection for my lens with no image quality issues at a very affordable price.

I needed an additional 52mm UV filter for a Nikon DSLR lens. I discovered this K&F Concept filter was available on K&F CONCEPT, which is reasonably priced. K&F has increasingly developed a pretty solid reputation for producing quality photography equipment (e.g., tripods and heads) & various other accessory products.

I am very pleased with this filter. The filter arrived attractively boxed in a cardboard outer box, as well as an additional inside snap-closing plastic box. The "kit" included the filter, an extra 52mm lens cap, a short camera wrist lanyard & a micro lens cleaning cloth.

All items in the kit present as clean & there isn't a hint of dust or film coating on the filter, which indicates this product was manufactured & packaged in clean environment. I really like the knurling that is present on the outside circumference of the filter; this allows for better gripping/control while handling the extremely lightweight filter & attaching it to one's lens. The K&F filter screwed very easily onto the lens, indicating good machining of the filter's matte finish aluminum frame.

I highly recommend this attractively priced, well-made K&F Concept UV lens filter.

I recently tried out the 52mm Clip-on ND2-400 Phone Camera Lens Filter by K&F Concept, and it's transformed my phone photography experience. This versatile filter offers a wide range of light reduction options from ND2 to ND400, allowing for creative control over exposure in various lighting conditions.

The clip-on design makes it compatible with a range of smartphones, including the latest iPhone models, ensuring that I can achieve professional-quality results with my mobile photography. Whether I'm capturing landscapes, portraits, or action shots, this filter helps me achieve the perfect balance of light and shadow.

Overall, I highly recommend the 52mm Clip-on ND2-400 Phone Camera Lens Filter to any smartphone photographer looking to elevate their images. It's a compact and convenient accessory that delivers impressive results, making it a must-have for mobile photography enthusiasts.

"Every lens should be equipped with a high-quality UV filter for protection. This 52mm Nano-X circular polarizer filter and MC UV protection filter kit from K & F Concept has such a filter. The kit also includes a circular polarizer filter and 2 high-quality lens caps. The 52mm UV filter has found its permanent place in my Canon EF-M 55-200mm STM lens with image stabilization, and the circular polarizing filter will serve as a welcome extra for several other lenses so I don't have to play "switch filters" between them. The included lens caps are very nice, but I find that it sometimes takes a bit too long to remove them, and I prefer the clip-on style that can be removed instantly.
Both filters improve image quality by removing glare and haze, respectively."

52mm ND2-ND32 (1-5 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens. What can I say? Unusual. Being able to adjust the ND filter and polarization at the same time without swapping the filters is super handy. Quick adjustments can make all the difference between getting the perfect shot in the moment or the perfect video pan. I have a Sony ZV-1 with a 52mm adapter for the lens and it threads in seamlessly and smoothly with no issues. Although my camera is equipped with a built-in ND filter. The K&F goes even further by having more control over how much light my camera picks up. The polarization aspect of the K&F further enhances the image quality.

I originally bought this UV filter for my Air 2S drone to protect the camera lens from dust and dirt caused by flying the drone. The drone itself comes with just a rim frame with no lens for the camera. Right off the bat, this item feels well made. In that sense, I'm new to camera drones and filters. Just buckle up and do what it says. I live by a lake and fly over it all the time. This is from the other night with a longer exposure. Works as advertised.

While they are not B&W or even Tiffen, I do like K&F Concept filters. Their filters tend to be well made, have a minimum of distortion and colorization especially considering their reasonable price. The 52mm Nano-X Black Soft Filter is another example of a well made, inexpensive filter.

Keep in mind that this is a special effects filter. It won’t be much value in normal, everyday photography. It is a Diffusion Effect filter. These filters were very popular in Hollywood films especially in the 1940s and 1950s. The were used for reducing blemishes and wrinkles on actor’s faces (especially on women) and for creating glowing effects. However, if you need or want these kinds of effects in your images, the K&F Concept 52mm Nano-X Black Soft Filter will do the job at a reasonable cost.

Overall very happy with the filter. Great quality. I bought the 52mm version. Used 2 of my kit lenses and no problems. Very easy to install and remove from the lens. Easy to clean. Should last a very long time.
