Reduction ring for 72mm magnetic filter

You have lenses of various sizes and 72mm filters?
There's no need to get a set of magnetic filters for each size.
You can use the magnetic filters of the diameter of your largest lens and then simply use magnetic step-up rings for your other lenses.

Note, it is not possible to stack magnetic reduction rings.
However, you can mount a magnetic reduction ring on a standard reduction ring.
