NiSi S6 150mm Filter Holder Adapter Ring for Canon RF 10-20mm f/4 L IS STM

The NiSi S6 150mm Filter Holder Adapter Ring is a dedicated mount designed to enable use of the NiSi S6 150mm Filter Holder System on the Canon RF 10-20mm f/4 L IS STM ultra-wide-angle lens. Constructed from durable aluminium alloy, this adapter ring slides securely over the integrated lens hood and tightens with a locking collar for a reliable connection. The adapter accommodates NiSi S6 circular filters including polarisers and UV filters, with external dials enabling independent rotation of compatible polariser filters. Once mounted, the S6 filter holder attaches with a pull-and-release locking pin, allowing 360-degree rotation for graduated neutral density and other position-sensitive filters. Installation and removal are quick and simple without removing the lens from the camera.
