K&F rarely disappoints me. THis filter and lens cap work great. I have found no issues with it at all. It just works.

I've been a big fan of K&F glass and optical performance. They may not be the best performer overall, but I feel they are definitely the best value in terms of cost to performance. The K&F magnetic MC UV lens filter continues to meet the expectations I've come to hold after using K&F filters for so long. Magnetic systems are fast, convenient, and becoming more and more mainstream, especially with stacking filters. The K&F magnetic system is also quite strong and I couldn't get the lens cap to fall off with my typical jostling movements, such as swinging my camera down, jumping up and down, or going up and down stairs. This worked both when I had the camera with a neck strap and when mounted to a backpack clip. It's safe to say that everything will stay put for my use scenarios.

Really nice magnetic system for filters and reasonably priced. Picked this up for my EF 24-70 f2.8 and thought it would be worth the risk to see if magnetic filters were worth the time and trouble. The glass on the UV filter in the kit seems to be good quality and the magnetic option is going to make adding filters a breeze. Pics taken with my 5D Mk IV were the same with the K&F filter as those taken with my B&W and Hoya filters. Considering my B&W and Hoya filters were both right at $100, I'd say the K&F at around $50 is a bargain. I'll have to use it quite a bit more in less than desirable conditions to see how it fairs with dust and water. K&F Reportedly uses Japanese Optical Glass or Schott Glass which are both top rated glass for filters or lenses. Overall, I'd say the Nano-X series is well worth the money at half the cost of other name brand filters.

The purpose of this filter isn't necessarily to change any of the visual characteristics of whatever I'm capturing on my camera (though K&F does make filters like that). I think it's the opposite. I think purpose of this seems to be to provide a layer of protection for my lens *without* changing what is captured. I'd much rather replace a $35 filter than my entire lens. The added bonus is that it comes with a magnetic lens cap designed specifically for this. I'm liking this enough that I'm considering picking up other K&F filters from this same series (Nano-X series) so that they'll be compatible.

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.
