NiSi Filter Holder S6 Adapter For Sigma 14mm F1.4 DG DN (Adapter Only)

NiSi Filter Holder S6 Adapter for Sigma 14mm F1.4 DG DN – Enables NiSi S6 150mm Filter System

Designed to enable the use of a NiSi S6 150mm Filter Holder System on a Sigma 14mm F1.4 DG DN, this adapter ring provides a direct and reliable connection between the lens and the NiSi S6 filter ecosystem. It is offered as the adapter-only option and is also included in the NiSi S6-Kit for the above lens.

What this adapter does

This adapter slides over the lens’ integrated hood and tightens to secure the connection. Once fitted, it lets you mount a NiSi S6 Filter Holder Frame to use 150mm-series filters on the Sigma 14mm F1.4 DG DN. In short, it converts the lens to accept the NiSi S6 150mm system while keeping the lens attached to the camera.

How it works — quick installation and rotation

• Slide the adapter ring over the integrated hood of the Sigma 14mm F1.4 DG DN and tighten to secure.
• Attach a compatible polarizer to the adapter ring; the adapter’s external dials allow independent rotation of the circular polarizer so you can adjust its effect.
• Place a NiSi S6 Filter Holder Frame over the adapter ring and use the holder’s pull-and-release locking pin to secure it.
• The locking pin provides a reliable, adjustable connection and allows the filter holder to rotate 360°, enabling precise positioning for graduated neutral density and other filters that benefit from varied placement.

Durability and handling

For durability, the adapter ring features an aluminum alloy construction. In addition, the design allows very quick installation and removal without removing the lens from the camera, so you can change setups fast on location or in the studio.
