I’ve wanted a magnetic filter kit for a long time, and hey, it’s Christmas! So why not? This K&F Concept kit has all the filters I use - a CPL, mist and variable ND. I was getting so tired of screwing filters on and off all the time that I sometimes just couldn’t be bothered. The magnetic set up solves that. It’s just click on and off, or stack them if you want. I have a bag-full of screw-in K&F filters and I’ve had no issues with their quality or optics - they’ve been (and are) excellent. For me K&F is that sweet-spot in quality and price where something like a NiSi filter is way too expensive and the opposite end (no names) just absolute junk. I wish the magnetic kit came with a variable 10-stop ND filter, though. The ND2-32 the kit comes with is only up to 5 stops. But I have a screw-in K&F ND3-ND1000 so I’m covered if I really need 10 stops. The kit comes with a pouch, which is a bonus, and a lens cap, which is handy. I’ve used the kit several times now and it’s been terrific. No real issues, although it took a little getting used to using the 2-in-1 CPL and ND filter. And the adapter ring could do with a bit more magnetism. But the quality of the glass is there - no big X across the image when using the variable ND filter for example. Overall the kit is easy to use and good value for money. It’s such a relief to not have to use screw-in filters any more. Recommended.
