Line up the lens filter with the adapter ring and the magnets will click together.

Switch and stack

Additional magnetic filters can be stacked on top of each other or quickly swapped out by gently pulling the filter from the adapter ring.

More filters in magnetic

Purchased the Urth magnetic kit of 4 filters and it’s brilliant but…looking at other Urth creative filters and sadly, not there for magnetic. Hope you extend your range of magnetic filters soon - please & thank you

Works Well

I didn't realize that the kit came with the a ring so I have an extra but it works with one of my other lenses. You do get some vignetting if you use it on a CPL, with or without a second filter, as a result I decided to order the URTH CPL.

Never losing a lens cap ever again
