The NiSi 70x80mm Nano IR Neutral Density filter is specially designed for landscape photographers. This filter is made from high quality optical glass (not rasin) with nano coating to prevent losing any single bit of detail. Neutral density filters do not affect the coloration of the image and the 1.8 density provides a 6 stop reduction in light from entering the lens.åÊThis filter measures 70mm x 80mm and is compatible with the NiSi 70mm M1 Filter Holder.
The NiSi 70mm filter system is great for compact and mirrorless cameras with lenses that have a standard filter thread from 39mm to 58mm.
By using neutral density filter the camera isåÊvulnerable to infrared light which will cast the unwanted red color to the photos when shotting at small aperture. Nisi added the infrared protection coating layer to this filter which help to eliminate the infrared light through the lens to bring back the nature color.
