Description
The NiSi Swift True Color Pro Nano CPL for True Color VND and Swift System reduces glare and reflections from non-metallic surfaces, increases saturation and vibrancy in the sky and foliage while ensuring true color reproduction is at its best by eliminating the warming effect that many polarisers create. Our True Color CPL removes the warm tone seen with other brands of CPL filters and provides a closer true color representation of the scene.
A Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies, foliage, and allows the camera to capture what is under the surface of shallow water.
Our proprietary NiSi Pro Nano Coating helps to reduce unwanted reflections and provides a waterproof and scratch-resistant layer to assist in the cleaning of unwanted fingerprints, dust and water stains. The NiSi Swift True Color Pro Nano CPL Filter has a removable control handle for easy rotation.
The NiSi Swift System works seamlessly with the NiSi True Color 1-5 stop VND Variable ND filter allowing the capability to be expanded by adding extra filters simply by pressing them on the front of the NiSi True Color 1-5 stop VND Variable ND filter.
Adding the NiSi Swift True Color Pro Nano CPL Filter, the NiSi True Color 1-5 stop VND Variable ND filter is expanded to a 1-5 VND filter with CPL. Or use the NiSi Swift True Color Pro Nano CPL Filter with the optional adaptor ring (Sold separately) and attach it directory to a lens.
Stacking multiple filters can introduce vignetting when shooting with wider focal lengths. See the suggested focal lengths below to avoid vignetting.
Swift in Video Mode:
True Color 1-5 Stops VND + 1 Swift filter = No vignetting at 18mm (Full Frame)
True Color 1-5 Stops VND + 2 Swift filter = No vignetting at 20mm (Full Frame)
Swift in Photo Mode:
Vignetting can vary from lens to lens based on design, breathing and focus distance. These suggested focal lengths are a guide at infinity focus:
True Color 1-5 Stops VND + 1 Swift filter = No vignetting at 20mm (Full Frame)
True Color 1-5 Stops VND + 2 Swift filter = No vignetting at 28mm (Full Frame)
