The NiSi 150x150mm Nano IR Neutral Density Filter ND32000 (4.5) 15 Stop is a Neutral density (ND) filter that uniformly reduces the amount of light entering the lens. ND Filters can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed. ND filters are also helpful when the contrast between the highlights and shadows is too high to get a quality exposure.A 15 stops filter can be used to achieve very long exposures in the middle of the day and with this filter, exposures upward of 5 minutes can be achieved even during bright sunshine.
NiSi ND filters do not affect the colouration of the image, offer a true to life colour and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. By using neutral density filter the camera isvulnerable to infrared light which will cast the unwanted red colour to the photos when shooting at a small aperture. NiSi ND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true to life colour.
The NiSi 150mm filter system is great for cameras with lenses that do not have a standard filter thread.
This 150mmx150mm filter is compatiblewith the NiSi 150mm filter system.
