Along with a filter holder you will also need an adaptor
One Handed Operation
With its innovative snap-lock mechanism it makes attaching and detaching the holder fast and secure. The X100 Holder has been designed for easy one-handed operation with a unique and oversized CNC machined Snap-Lock knob.
Press the filter holder against the adapter ring and it immediately locks into place with a snap!
That way you can focus on the shot and not the holder every time you detach/reattach to the adapter ring.
