have been very skeptical about magnetic mounting system for lens filter. Now that I’ve been using the K&F magnetic filter with lens cap, I’m pleasantly surprise with how well it works. I’ve struggled with plastic lens cap popping off when I’m walking around or placing the camera in the bag. The K&F magnetic filter doesn’t come off accidentally in the bag or while I walk. The cap snaps onto the filter very securely and will not come off unless you physically pull it off. The UV filter is very nice and clear. I had a few water droplets on the filter and it beads up in a way that makes it easy for me to dab away with the microfiber cloth. The filter itself is clear and doesn’t hinder the image quality or the auto focusing features of the camera. I’m looking forward to trying out other filters in K&F magnetic system. So far I’m very impressed with the set and I would highly recommend these to photographers who need a quick change system for their filters.

bought this for a Canon RF 600mm f/11 lens. I personally don't think that a UV filter provides much in terms of eliminating any impact of cutting back UV light hitting your sensor, but on expensive lens I will almost always use a UV for protection (along with a lens hood). This filter is part of K&F's Nano-X series of magnetic filters, and you can add other Nano-X filters to the UV filter here that screws in. The included lens cap also attaches magnetically. The magnet is VERY strong. I will consider other Nano-X filters, and adapt them via a step up ring to my other Canon lenses which are mostly 77mm. Recommended.

I've been a photographer for many years - I'm really enjoying this concept compared to the fiddly traditional plastic squeeze type protectors.

The K&F Concept X-Series 77MM Magnetic MCUV Filter leaves a very positive impression. The workmanship is top-notch – the filter feels robust and high-quality, which is exactly what you'd expect from K&F. As usual, it simply screws onto the lens, which works absolutely seamlessly. A particular highlight is the magnetic lens cap. It's quick and easy to attach, which I particularly like when things are in a hurry. An additional filter can also be attached magnetically, making handling much easier. This eliminates the need to mess around with screw systems, which is definitely an advantage during longer photo or video sessions. The filter also impressed with its image quality. There's no color shift or loss of sharpness – the image remains clear and undistorted. The filter reliably protects the front lens element from damage without any noticeable loss of quality. For photographers and videographers who are on the move a lot or who value quick and convenient handling, this filter is definitely recommended. All in all, a solid product that K&F delivers with the usual quality.

Might take a little bit to get used to the hand motion to take them off as the magnets are strong but for me thats a good thing, id rather them stay on there better than fall off at the lightest touch, everything attached and fit very well, I bought it in 67mm, 77mm, and 82mm and all of them were applied without issue and work great.

Surprised to have found a top price on Amazon when there are plenty of sellers specializing in photography. The motorcycles themselves are essential to have. I have an R50 and it is a pleasure to work with, soon a good trip to test it thoroughly. I used the product on the Canon RF-S 18-150mm F3.5-6.3 is STM is Stabilized Lens for Canon RF APS-C Camera, to protect a 500 euro product. I hope my comment is useful, thank you for putting it up.

It is traditional to have excellent quality products, I have more items from the same brand and I definitely recommend it! It protects the lens from scratches and dust.
