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."

They screw on pretty smooth it have a quality threads, and it work just fine. Perfect for someone who's only going to be casually using their step up rings, I am a professional photographer & I was looking same filter Ring Adapter & I order this product which is very helpful for me when I use multiple filter with my Nikon 5300 camera lens. During photo-shoot many time we have to change camera lens along with filter also, so using this ring it is very helpful for me, these rings get there job done, and don't get stuck. Please note - these are step-Up rings also have Step Down Rings total 18 rings.

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.

This filter works perfectly for me and I am very happy with the results I got while using it. It is worth noting that the size of lens cap you need once it is fitted on your lens increases. I bought the 49mm and had to increase my lens cap size to 52mm to accommodate the larger thread size on the front. This wasn't a big deal though as I already had a 52mm lens cap lying around. There is a size chart on the company's website that tells you what size lens cap you need based on what size filter you buy. Hope that helps

Overall very satisfied 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 long time.
