Circular polarising camera filter NiSi TC CPL SWIFT 77 mm, double-sided coating

The NiSi TC CPL SWIFT 77 mm is a circular polarising camera filter with a 77 mm thread and double-sided Pro Nano coating. It reduces reflections and glare from non-metallic surfaces, increases color saturation and contrast in skies and foliage, and preserves a neutral, true-to-scene color balance by eliminating the warming cast common to many polarizers. The filter is compatible with the NiSi Swift System and can be attached directly to a 77 mm lens or mounted to the NiSi True Color VND to add polarizing capability.

Advantages

This CPL filter cuts reflections and visible glare while improving tonal saturation and reducing atmospheric haze, producing clearer skies and richer foliage rendering. NiSi's Pro Nano double-sided coating adds waterproof and scratch-resistant properties and eases cleaning of fingerprints, dust, and water marks. The removable control handle allows convenient rotation for precise polarization adjustment.

Suitable for

• Landscape and outdoor photography to deepen sky contrast and reduce haze
• Product and still-life photography to minimize surface reflections
• Architectural and real-estate photography to control window and water reflections
• Use with NiSi Swift System or directly on 77 mm lens threads

When it may not be suitable

Polarizing effects are angle-dependent and work best at certain sun positions; results may be limited in low-angle or diffuse light conditions. It does not reduce light uniformly like neutral density filters and is not intended for exposure reduction purposes alone.

Key specifications

• Filter type: Circular polarizer (CPL)
• Thread size: 77 mm
• Coating: Double-sided Pro Nano anti-reflective, waterproof and scratch-resistant coating
• Color rendering: True color reproduction without warming cast
• Compatibility: NiSi Swift System and mounting on 77 mm lens thread; can be combined with NiSi True Color 1–5 stop VND
• Finish/colors: Black/grey
• Quantity: 1 piece

How to use

Screw the filter onto a lens with a 77 mm thread or attach it to the NiSi True Color VND when using the Swift System. Rotate the removable control handle while viewing the scene in the viewfinder or on the camera screen until unwanted reflections are minimized and the desired increase in color saturation and contrast is achieved. Clean the coated surfaces with a soft microfiber cloth and appropriate lens cleaner to maintain coating performance.

What to consider before purchase

• Confirm your lens thread size is 77 mm
• Decide whether you will use it directly on the lens or with the NiSi Swift System/VND
• Polarizers affect exposure slightly—be prepared to adjust settings if necessary

Usage recommendations

For best results, use the CPL at roughly a 90-degree angle to the sun and rotate the filter while observing the effect in the viewfinder. Avoid stacking many filters to reduce the risk of vignetting on wide-angle lenses.
