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.

I 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.
