NiSi JetMag Pro 77mm-82MAG マグネットアダプターリング

The magnetic connection is incredibly strong — I was worried it would be flimsy, but it locks on tight and makes swapping filters effortless. This little ring has saved me from buying a whole new set of filters for my lens collection.

Finally I can use my 82MAG filters on a 77mm lens without any wobble. The magnetic hold is impressively strong, and threading on the ring was smooth right out of the box. Exactly the adapter I needed for my kit.

Swapped it onto my 82mm lens setup and the magnetic mount is rock solid—no wobble even with a heavier filter attached. Saves me from buying a whole new set of filters for my other lenses.
