The title of this review pretty much says it all about the K&F Concept 52mm MCUV lens protection filter; even the name of the product indicates its most important function. This type of filter is primarily used to protect our expensive camera lenses, and K&F directly names its product as a “lens protection filter.” Therefore, this product appears to be well made and, when used, did not cause any aberrations, glare or ghosting in images taken with the filter, whether directly on the lens or in combination with other filters. It is very thin and has both an internal and external thread of 52mm. In comparison, the K&F UV filter is much thinner than the same type of filter sold by other manufacturers, with no noticeable difference in photo results. My only complaint is that, like many other K&F filters I've tried, attaching the K&F filter can be a bit tricky and produces a more noticeable "scratching" sound than other filters when screwed onto the mount . However, I did not find any negative results that could be attributed to this sound or its creation. All in all, I think the K&F Concept 52mm MCUV Lens Protection Filter is a product that should definitely be on your potential purchase list if you are looking for a UV protection filter. The competitive price and thin form factor, as well as the lack of obvious drawbacks, are clear pluses, which is why I rate this lens a solid 5-star product.

Comes with cloth, cap and wrist strap. The 52mm adapted perfectly to my lens. The filter is circular and allows you to vary the reflections to blur them or on the contrary to accentuate them. Darken the shot a bit to compensate with the camera settings.

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.

K&F Concept 52mm Circular Polarizer Filter with Lens Cap Cleaning Cloth Is well made and easy to use. Feels very durable but light weight. It looks good on my camera set up. It’s a great product for the money.

We got the 52mm filter and lens cap for my husband’s Canon M50 with a 200mm lens, and it fits perfectly.

It all feels very good quality, and he has had no issues with it.

"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."

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

I use the 67mm version of this filter. Since there are no external threads to mount a hood (I use this with a stepup ring for other lens sizes), I use a 67mm Amazon product ($9.50 for two) "67mm Camera Lens Hood - Rubber - Set of 2 - Collapsible in 3 Steps - Sun Shade/Shield", Mount the rubber hood BEFORE the VND, fold the rubber back over the lens, then mount the VND, set it where I want it, then pull the rubber hood out over the VND adjustment ring. A little awkward, but it works.
