The K&F Concept 72mm magnetic filter kit is a fantastic balance of speed, quality, and portability. The magnetic swap system makes shooting faster and smoother, the coatings hold up impressively in real-world conditions, and the CPL/ND combination adds a lot of creative flexibility. From vibrant skies and contrast-rich B&W images to dreamy long-exposure water effects, the kit delivered reliable, high-quality results.
Just be aware of the quirks: the thin adapter ring can be fiddly to handle, and stacking on wide-angle lenses increases vignetting. For serious long exposures, you’ll still want to add an ND1000.
That said, the build quality really impressed me. While I don’t recommend dropping them, it’s reassuring that when I accidentally did, they came away without a scratch. The magnetic lens cap also held firm the entire time, unlike another magnetic set I tried previously, where the cover kept slipping off — and eventually got lost because it wasn’t strong enough. With this K&F kit, everything stayed secure, making it a system I’d happily keep in my bag for everyday use and travel photography alike.
