A fantastic invention for using magnetic filters. Besides being a 77-82mm step-up adapter, it's magnetic, so you don't need a separate magnetic adapter ring. This reduces the thickness of the stacked filters and the risk of vignetting—a real game-changer. And pay attention to this because it's not a trivial matter. Here's an example of using a magnetic ND filter:
FIRST EXAMPLE (Using a non-magnetic 77-82mm adapter). The order would be: 77-82mm non-magnetic adapter + Magnetic ring + ND filter.
SECOND EXAMPLE (Using the magnetic 77-82mm step-up adapter). It would be: 77-82mm magnetic step-up adapter + ND filter.
As you can see, the thickness is reduced. If you've never used magnetic filters before and want to get started, I hope this has been helpful.

It does the job; the magnet is very strong, and the protective cover doesn't come off easily.

This magnetic adapter ring allows me to use my 82mm magnetic filter kit on my 77mm lens, making it a great system and buy.

I have downsized from my Canon 5Dmk4 and "L" lenses to 2 R bodies and RF lenses. Now all Canons L lenses take a 77mm filter which is great , but the new RF lenses take a 67mm filter, so rather than buy a new range of filters just stuck this filter adapter on my 67mm lenses and dont have to even think about different sizes. Its not a Normal step up size, it would be 67/72mm, so a blessing to us Canon users

Screw it on and leave it there. Will make swapping filters much faster. Highly recommended!

Very happy with this product magenta work strong and securely keep filters and cap on. I bought the 82mm magnetic kit as that’s my biggest size lens and then purchased this adapter to use with the majority of my other lenses which are 67mm threads.
