My Personal Experience Tested & Reviewed

As someone always on the go, switching between lenses for different shoots was eating into my time. That's why I grabbed the K&F Concept 77-82mm Magnetic Filter Adapter Ring. After a few weeks of use, here's what I think.

First off, it's a game-changer. No more fumbling with multiple filters; this adapter lets me use just one magnetic filter across various lens sizes. It's made a world of difference in my workflow. The magnetic attraction is solid too, filters stay put even when I'm moving quickly between shots.

I love the durability of this thing. Made from aviation aluminum, it feels robust and has taken a few bumps without any issues. Plus, the quick release makes swapping filters a breeze - a huge plus for someone like me who's often juggling multiple tasks on set.

One minor downside is that it only fits K&F Concept brand magnetic systems and is designed specifically for 77mm lenses. If you're not already invested in their system or have different lens sizes, this might not be the best fit.

But if you're a professional photographer using K&F Concept filters and lenses, this adapter ring is a must-have. It's saved me time and hassle, allowing me to focus more on getting the shot right instead of fiddling with equipment. Worth every penny at $24.99.

What Buyers Love

Customers rave about the K&F Concept 77-82mm Magnetic Filter Adapter Ring's versatility and convenience. It allows for quick filter swaps thanks to its sturdy magnetic attraction, making it perfect for those who use multiple lenses with different filter sizes. One user downsized their equipment but kept using their existing filters effortlessly with this adapter ring, saving money on new purchases. **

Things to Consider

While the magnets are strong enough for most uses, one reviewer noted that they were not powerful enough to hold their variable neutral density (VND) filter, causing it to fall off. However, they confirmed it works well with their Black Mist filter. Additionally, it's designed specifically for K&F Concept magnetic systems and fits only 77mm lenses, so ensure compatibility before purchasing.
