NiSi manufacture a wide range of screw-in circular filters to meet the needs of all photographers; professionals and amateurs alike. NiSi Circular filters are made of the highest quality optical glass to preserve the finest detail in your images.  Our filters are the high quality solution for photographers who want to extend the boundaries of their creativity without the use of holder based systems. NiSi circular screw-in filters are available in all popular sizes up to 95mm.

The NiSi Circular Filter Range

  • UV filters help to protect your image from the negative effect of ultraviolet rays (blue shades, haze effect and colour tone alteration.) Made with the highest quality neutral optical glass, they are also used to protect the front lens of your lens without losing detail.
  • Circular Polarisers (CPL) allow you to manage reflections and are great for shooting water where the reflection on the water would reduce visible detail. They also serve to further saturate and enrich colour in your shots. Also available in the Landscape version with Titanium structure and accentuated polarisation. The “Circular” in Circular Polarisers refers to the nature of the polarisation, not the shape of the filter.
  • ND (Neutral Density) filters are used to extend shutter speeds or use wider apertures even in bright conditions. One of the most common uses is to decrease the depth of field with strong brightness, to make the water look like silk and to make people disappear from the crowded areas. 3, 6, 10 and 15 Stop screw-in ND filters available.
