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.

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.

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.

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.

This is a great combo filter. It comes with a very nice leather-like pouch and feels sturdy and nice. I got the 67mm and it fit perfectly on my Canon RF 85mm f2.0 prime lens -- look on the rear of the lens cap for your lens' diameter. The lens cap fits on top of the filter just fine.

I also have an RF 35mm f1.8 with a 52mm diameter -- I ordered the K&F Concept 52mm to 67mm Step-Up Lens Filter Adapter Ring so that I can easily switch this expensive filter back and forth rather than having to buy two filters.

One thing to beware of is that it seems like it would be very easy to over tighten this and get it stuck. It doesn't screw on and stop -- you can keep turning it. I nearly went too far the first time I put it on so now I don't tighten it as far as I would like.

The filter itself works wonderfully. I like the combined ND and CPL filters. The ND is for removing some light when taking videos (since you can't really adjust shutter speed for videos) and the CPL is for removing light reflections for videos or photos. It makes it look like when you put on a fancy pair of polarized sunglasses on a bright day.

I do wish the variable turning handle had some hard stops or even any kind of tactile click when it gets to the next stop, but it is smooth and so you have to have it away from your face and look to see when the dots match up visually rather than being able to click through the settings with the camera up to your face the whole time.

Overall though, this is a terrific filter with high quality engineering from a trusted brand. Would highly recommend this.

"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."
