NiSi Square Nano IRGND Soft
A soft graduated IRGND filter designed to balance bright and dark areas of an image, such as a bright sky against a darker foreground. The filter is constructed from H-K9L optical glass for high colour reproduction and is optimised for digital sensors.
NiSi Optical Nano Coating on both sides of the glass reduces colour shifts and ensures cleaner blacks by maintaining neutrality between the visible and infrared spectrums. This coating also makes the filter water and oil repellent. It is recommended for use with normal and wide-angle focal lengths and produces no vignetting.
