The 46mm NiSi Huc IR ND Filter provides a 6-stop exposure reduction. Its 1.8 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. This filter is constructed from optical glass for clarity as well as color fidelity. It also features a slim and durable aluminum alloy filter ring that minimizes the potential for vignetting while remaining lightweight.

NiSi HUC PRO Nano IRND Filter Reviews
Works great!

Darkens the image in extreme bright conditions so I can film at t 2.8 without needing a matte box. Haven’t noticed a color shift or vignetting.
Perfect for shooting 24fps in bright daylight

No color cast at all. If you need to shoot 24fps in bright daylight, get this. You will not regret it. A 6-stop ND is essential for this. Highly recommended.

Are these the same glass as that found on their cine versions?
I contacted NiSi concerning your inquiry. According to the manufacturer, yes, the NiSi 77mm HUC PRO Nano IRND 1.8 Filter (6-Stop) uses the same optical grade glass as used in their standard square filters and their Cinema line filters. They state the only filters in their inventory that use B270 Schott glass would be the filters in their 100mm wide Explorer line, which are not available in the circular format.
