NiSi Filter Circular For S6 Pro NC UV

NiSi Filter Circular For S6 Pro NC UV – Absorbs Ultraviolet Light to Reduce Bluish Cast

This NiSi Circular UV filter is designed for use with the NiSi S6 150mm filter holder system. It screws into the NiSi S6 150mm filter holder adapter ring after you remove the kit’s included Pro Screw-In Circular Polarizer Filter. When mounted, the filter absorbs ultraviolet light and helps reduce the bluish cast that can appear in daylight conditions.

Compatibility and mounting

Install the filter by screwing it into the S6 150mm filter holder adapter ring once the Pro Screw-In Circular Polarizer has been removed from the kit. The filter is specifically made to work within the NiSi S6 150mm system. Note: if you use an older generation S5 adapter, the S6 holder frame must be used in combination with that adapter.

Optical effect and image quality

The filter absorbs ultraviolet light so that less UV reaches your camera sensor. As a result, it reduces the bluish cast that sometimes appears in both video and still photography under daylight containing ultraviolet components. At the same time, this filter does not introduce additional coloration or alter contrast, and it does not require adjustments to exposure when you use it.

How it works (measured performance)

The NiSi S6 PRO NC UV progressively eliminates ultraviolet waves before they reach the sensor. Specifically, the filter absorbs 50% of ultraviolet light waves at 395 nanometers, reducing UV content and helping to limit the light entering the camera to the visible spectrum. This process helps preserve color accuracy across the frame in mixed daylight conditions.

Materials and coatings

The filter uses optical glass to maintain clarity and color fidelity while providing high transmission of visible light. The filter achieves approximately 98.5% transmission of visible light, so it keeps images bright while filtering out ultraviolet wavelengths.

Additionally, NiSi’s Pro Nano Coating reduces unwanted reflections and creates a waterproof and scratch-resistant surface. This coating also makes it easier to clean fingerprints, dust, and water stains from the filter surface.

Smart FAQ

Question: Will this filter change the color balance or contrast of my images?
Answer: No. The filter reduces ultraviolet light and the bluish cast caused by UV, but it does not add coloration or alter contrast, and it does not require changes to exposure.

Question: How do I mount the filter in the NiSi S6 system?
Answer: Screw the filter into the NiSi S6 150mm filter holder adapter ring after removing the kit’s Pro Screw-In Circular Polarizer Filter. The filter is specifically designed for the S6 150mm holder system.

Question: Does the filter help with reflections and cleaning?
Answer: Yes. The NiSi Pro Nano Coating reduces unwanted reflections and provides a waterproof and scratch-resistant surface, which also makes it easier to clean fingerprints, dust, and water stains.

Question: Can I use this with an older S5 adapter?
Answer: You can, but you must use the S6 holder frame in combination with the older generation S5 adapter to ensure proper fit and function.
