looked at a lot of different magnetic filter systems, but ultimately decided on the K&F filters. It was a great decision. I would have purchased from their new Pro lineup, but they weren't available at the time (at least in magnetic form). I keep one of these UV filters on each of my lenses permanently to protect them, so I attach them via the threads. It then becomes the magnetic base for my other K&F ND and CPL magnetic filters as well as the magnetic lens covers. All of the filters have threads, so they work either way. But when attaching a filter magnetically, the threads serve to keep the magnetically attached filters in place, which is great. Stacking the magnetic filters works perfectly as well, as the magnets are strong enough to keep everything in place and stable. All in all, these were far less expensive and yet more convenient than the other systems I looked at. I highly recommend them.

love it!!!! I got a step up adapter for my lens for this 77mm which is the size of the largest glass i've got. It's super nice to have just a magnet now and I can take it on and off. At least the cap you can with this product, I have another set of magnetic filters which work seamlessly with this product. The cap however can easily come off if you stack more of the magnet filters (which in my case are more K&F ones). Not a huge deal, the lens isn't very expensive and I don't really take it out in rugged environments. Overall can recommend for anyone looking to get into the magnetic filter ecosystem with something functional too.

It’s always been suuuuper annoying having to change filters especially when you on a shoot or on back to back shoots. It can get hectic but this definitely helps!

This filter fits my Nikon 17- 25mm f2.8 lens perfectly. It has no vignetting. Contrast and sharpness seem to be equal or better than the old Canon filter it is replacing. Granted it is through a visual inspection of images not a scientific test. The lens cap fits snugly. A standard filter also works should I misplace the magnetic one. Good value for the price.

To be fair, I don't use the UV filters for UV protection. I haven't done photography long enough to know the difference between photos with or without the filter. What I can say, however, is that UV filters are a great addition to a camera lens to protect the glass from dust, liquids or scratches. For the price, its a very valuable addition to protect your lens investment.

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.
