Marumi M100 100mm Magnetic Filter Holder

The Marumi M100 is the heart of Marumi's magnetic 100mm filter system, letting landscape and long-exposure photographers swap square filters in seconds. Instead of buying filters for every lens, you fit one aluminium holder and use the same filters across your kit.

Strong magnets grab each filter with a single touch and hold it flush, preventing the light leaks common with slot-in holders. Stack up to three filters, and add the optional M100 circular polariser in the centre, rotated by a gear on the base of the holder.
