NiSi Filter Holder S6 Alpha Kit For Sigma 20mm F1.4 DG

NiSi Filter Holder S6 Alpha Kit for Sigma 20mm F1.4 DG – 150mm filter system with 360° rotation

The NiSi S6 ALPHA 150mm Filter Holder is designed for landscape and ultra-wide-angle photography. It accommodates two 150mm wide filters (2mm thick) and offers full 360 degrees of rotation. The kit includes an adapter made for the Sigma 20mm F1.4 DG lens, allowing you to use large 150mm filters with that specific lens.

Secure and smooth locking system

The S6 features a locking mechanism that keeps the main holder firmly in place. An integrated wheel lets you rotate the holder smoothly and lock it at the desired position. This design gives you precise control over filter orientation and helps maintain a steady setup during shooting.

Reduce ghosting and flare for clearer images

NiSi applies a matting treatment to the main adapter that matches the approach used in high-end lens hoods. This treatment reduces unwanted reflections and helps minimize ghosting and flare when using filter combinations, particularly on wide focal lengths.

Fast installation and an efficient workflow

The S6 ALPHA Filter Holder installs quickly and removes without taking the lens off the camera. Front clips securely hold the 150mm filters, so you can remove and replace filters rapidly during a shoot. These features help you keep shooting and maintain creative momentum in changing light and scene conditions.

Compatibility and expandability

The holder accepts NiSi 150mm square filters and is also compatible with S6 Circular Filters, including Polarizers (sold separately). This compatibility gives you flexibility to combine square filters with circular polarizers when your composition or lighting requires it.
