Category: S6 150mm Holder System

The NiSi S6 150mm Filter Holder Adapter Ring is designed to enable the use of a NiSi S6 150mm Filter Holder System on a Sigma 20mm f/1.4 DG HSM Art lens. The use of the S6 filter holder is easily accomplished by first sliding the adapter ring over the integrated hood of a lens and tightening.  The adapter ring accommodates a NiSi S6 Circular Filter for NiSi S6 including a Circular Polarizer and UV filter. When combined with the adapter ring, a compatible polarizer filter can be rotated to adjust its effect. Both the external dials on the adapter ring allow for the independent rotation of the circular polarizer.

A NiSi S5 150mm Filter Holder can then be placed over the adapter ring. After being fitted onto the adapter ring, the filter holder’s pull-and-release locking pin helps to provide a reliable, yet adjustable connection that allows the filter holder to be rotated 360°, permitting the use of graduated neutral density and other filters that are enhanced by varied positioning. For durability, this adapter ring features an aluminum alloy construction. The adapter allows very quick installation and removal without removing the lens from the camera.

Already own the NiSi S6 Holder Kit?  Simply add this adaptor to make it compatible with the Sigma 20mm f/1.4 DG HSM Art lens.

This is the adapter only and is compatible with the Circular S6 filters.  It requires an S6 Holder to work with 150x150mm or 150x170mm filters.  

Please note: If using this adaptor with the previous generation S5 system, ensure S5 circular filters are used with the S5 holder.

Abigail ★★★★★

The ring locks into the Sigma mount without any wobble, and it’s reassuring that the 150mm system stays flush even when I’m tilting the lens. Took a minute to seat it properly, but once it’s on, I trust it for long exposures.

Penelope Q. ★★★★★

The fit on my Sigma 20mm is precise and secure, so no worries about the filter wobbling during long exposures. It locks onto the lens smoothly and the S6 holder clicks right into place without any frustrating alignment fiddling.

Aurora Y. ★★★★★

Swapping from another filter system to this adapter was seamless—it screws onto the Sigma 20mm f/1.4 Art without any wobble. The S6 holder locks in tight and doesn’t cause any vignetting at f/16. Really happy with how solid everything feels for long exposure shots.
