NiSi offers a range of circular screw-in and square filter that are perfect for landscape photographers looking for a high quality and easy to use system. NiSi Square Filter Systems are available in 75mm for compacts and mirrorless, 100mm for most lenses including some wide-angle lenses with standard filter threads, 150mm for popular ultra-wide-angle lenses including the Nikon 14-24mm f/2.8, Tamron 15-30mm f/2.8, and the 180mm for other ultra-wide-angle lenses such as the Canon 11-24mm f/4L.
All NiSi square filters are Nano coated and offer true to life colour through IR technology. NiSi Filters are low reflection, are made from high definition Optical glass and offers double-sided waterproofing. By using neutral density filters the camera is vulnerable to infrared light which will cast the unwanted red colour to images. NiSi Filters have an added infrared protection coating layer to eliminate the infrared light through the lens to bring back the true to life colour.
