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

This NiSi S6 Adapter Ring lets NiSi's S6 150mm Filter Holder System mount onto a Canon RF 10-20mm f/4 L IS STM, a lens that wouldn't otherwise accept a standard filter holder. It slides over the lens's integrated hood and locks in place, so an existing S6 Holder Kit becomes compatible with this lens without buying a new holder. Because the CPL rotates independently via external dials and the holder itself rotates a full 360 degrees, graduated ND and other position-sensitive filters stay adjustable after the whole assembly is mounted.

• Lens-specific S6 compatibility: Adds S6 150mm Filter Holder System support to the Canon RF 10-20mm f/4 L IS STM via a slide-on, tighten-down fit over the lens hood.
• Independent CPL rotation: External dials rotate a compatible S6 circular polarizer independently of the holder.
• 360° filter holder rotation: A pull-and-release locking pin lets the holder rotate freely for repositioning graduated ND filters.
• Aluminum alloy construction: Durable enough for repeated quick installation and removal without taking the lens off the camera.
• Adapter only: Requires an existing S6 Holder for 150x150mm or 150x170mm filters; compatible with S6 circular filters.
