Key Features
Description
Description
The S6 ALPHA is NiSi's filter holder system built specifically to mount on the Sigma 20mm f/1.4 DG HSM Art's lens barrel, supporting two 150mm-wide filters (2mm thick) with a full 360 degrees of rotation. Because it's a dedicated fit rather than a universal clamp, installation and removal happen without taking the lens off the camera, and the front clips let you swap 150mm filters quickly between shots. The main adaptor uses the same matting treatment found in high-end lens hoods to cut down on ghosting and flare at wide focal lengths.
- Dedicated fit for the Sigma 20mm f/1.4 DG HSM Art: mounts directly to this lens rather than using a universal clamp.
- Two 150mm filters, 360° rotation: holds two 2mm-thick 150mm filters with full rotation for graduated ND positioning.
- Anti-ghosting matte treatment: same matting process used in high-end lens hoods to reduce flare at wide angles.
- Quick-release front clips: swap 150mm filters without removing the lens from the camera.
- S6 Circular Filter compatible: also accepts NiSi S6 circular polarizers, sold separately.
