NiSi Filter S5 Adapter For Sigma 14-24 F2.8 (Adapter Only)

NiSi Filter S5 Adapter For Sigma 14-24 F2.8 – Adapter Only with 360° Rotating CPL Compatibility

The NiSi Filter S5 Adapter for Sigma 14-24mm F2.8 adapts this wide-angle lens to the NiSi S5 filter system. It comes as an adapter only and requires the S5 filter holder and any filters to be purchased separately. The adapter lets you use the S5 integrated circular filter and supports a full 360° rotation for circular polariser (CPL) adjustments without vignetting.

Key features at a glance

• Specially designed to fit the Sigma 14-24mm F2.8 lens.
• Adapter only – the S5 filter holder and filters are sold separately.
• No vignetting when properly mounted with the compatible S5 holder and filters.
• 360° rotating capability for easy use of a CPL.
• Allows the use of an integrated Circular S5 Filter (sold separately).
• Constructed from aluminium alloy using CNC technology for precision machining.

Compatibility and system flexibility

This adapter integrates the Sigma 14-24mm F2.8 into the NiSi S5 modular system. If you already own an S5 holder, you can add this adapter to make that holder compatible with your Sigma lens. Conversely, the S5 system uses interchangeable adapters so you can swap adapters to support other lenses as needed.

Practical use cases

Use this adapter when you need filter control on the Sigma 14-24mm F2.8 while avoiding vignetting. Photographers and filmmakers who use circular polarising filters will benefit from the 360° rotation feature for precise control. Because the adapter works with the integrated Circular S5 Filter, you can add that filter type to your setup when required.
