Summary: Magnetic filter option for CU filters or non-magnetic filters is no
longer doable... my limited searching.
The Xume filter adapters come in limited sizes 46, 55, 62, 82 mm. One can pick
the 82mm and then use step up/down rings to adapt them to 77 or 72mm
filters/lenses. However, looking at this page, only the 46 and 82mm filter
holder are listed and the 82mm holder is listed as out of stock.
All the systems, Kase Wolverine, Freewell, Haida, ... I checked have the lens
adapter that attaches to the lens so you can then use a "magnetic" filter they
are happy to sell you.
BH shows 72mm and 58mm discontinued AND only the 46mm filter holder is listed.
Seems Manfrotto is dumping the Xume system as soon as stock runs out. Perhaps
too many have failed in the field so Manfrotto is axing Xume.
I did not find any other filter adapters other than Xume. Any advice would be
appreciated as the magnetic filter holder seems a great way to go for a CU
filter, but so far I can only find the lens adapters to go with magnetic
filters. Adapting an existing filter is no longer an option unless there is
