NiSi Filter S5 Circular UV NC (for S5 Holder)

NiSi Filter S5 Circular UV NC (for S5 Holder) – absorbs ultraviolet light to reduce bluish daylight cast

This NiSi S5 Circular UV NC filter is designed for use with the NiSi S5 150mm filter holder system. It screws into the NiSi S5 150mm filter holder adapter ring once the kit’s included Pro Screw-In Circular Polarizer Filter has been removed. In use, the filter absorbs ultraviolet (UV) light and helps reduce the bluish cast that can appear under daylight conditions with UV present.

Compatibility and mounting

Use this circular UV filter specifically with the NiSi S5 150mm filter holder system. Install it by threading it into the S5 150mm adapter ring after removing the Pro Screw-In Circular Polarizer included in the kit. Note that this filter cannot be used with the NiSi S6 filter holder.

Optical performance

The filter reduces unwanted blue casts in both video and still photography by limiting ultraviolet light reaching the camera sensor. The original text notes that, for the NiSi S6 PRO NC UV, 50% of ultraviolet light waves are absorbed at 395 nanometers, with shorter wavelengths progressively eliminated before that point. The S5 Circular UV NC helps preserve color accuracy across the frame by reducing the influence of ultraviolet light.

While using the filter, you do not need to adjust exposure settings, as it does not require exposure compensation according to the product information.

Construction and surface treatment

The filter is constructed from optical glass to support clarity and color fidelity. It provides approximately 98.5% transmission of visible light, maintaining scene brightness and detail while filtering UV.

NiSi’s Pro Nano Coating is applied to the filter surface. This coating helps reduce unwanted reflections and adds a waterproof and scratch-resistant layer. It also makes cleaning easier by assisting the removal of fingerprints, dust, and water stains.
