NiSi 75 x 100mm Nano IR Medium Graduated Neutral Density Filter

The NiSi 75x100mm Nano IR Medium Graduated Neutral Density Filter is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition is particularly useful for images that feature buildings, small mountains, and other elements that protrude high into the skyline.  The transition zone of a medium is 40% smaller than a Soft GND and is wonderful for shooting at sunrise and sunset.

NiSi GND filters do not affect the coloration of the image, offer a true-to-life color, and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail.  By using a neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shooting at a small aperture. NiSi GND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true-to-life color.

The NiSi M75 filter system is great for compact and mirrorless cameras with lenses that have a standard filter thread from 40.5mm to 67mm.  

This 75x100mm filter is compatible with the NiSi M75 filter system.
