NiSi Filter S5 Adapter For Sigma 14 F1.8 (Adapter Only)

NiSi Filter S5 Adapter For Sigma 14mm F1.8 – Custom Fit to Use with S5 Filter Holder

This NiSi S5 adapter is specially designed to fit the Sigma 14mm F1.8, enabling the lens to work with the NiSi S5 Filter Holder. The adapter ships alone and requires the S5 holder and any filters to be purchased separately. It provides a tailored connection between the lens and the S5 system so you can add S5 filters when needed.

Key features

• Custom fit for the Sigma 14mm F1.8 to ensure correct alignment with the S5 Filter Holder.
• Adapter only — the S5 holder and filters are not included and must be purchased separately.
• No vignetting when used as intended with the compatible S5 system and filters.
• 360-degree rotating design to allow the use of a circular polariser (CPL) and to adjust polarisation orientation.
• Constructed from aluminium alloy using CNC technology for precise manufacturing.
• Compatible with NiSi’s integrated Circular S5 Filter options (filters sold separately).

Compatibility and use

If you already own the NiSi S5 system, you can buy this adapter to make your existing holder compatible with the Sigma 14mm F1.8. The S5 system uses a modular adapter approach, which means you can swap adapters to support other lenses without changing the entire holder.

Materials and build

The adapter is manufactured from aluminium alloy and produced with CNC technology. This construction method delivers accurate tolerances and a reliable fit between the lens and the S5 holder.
