With a 46mm front filter thread design, the NiSi True Color ND-VARIO Pro Nano 1-5stops Variable ND is intended to fit into lenses and offers an exposure reduction of 1 to 5 stops. The entire image is darkened by the 0.3 to 1.5 density, enabling slower shutter speeds or wider apertures than are typically possible. Rotating the front filter ring, either with or without the supplied silver lever, allows you to easily alter the degree of density, assisting you in calculating the additional exposure time needed. You may more readily express movement by controlling the depth of field by adjusting your exposure duration or aperture. The smooth transition of density enables the photographer or videographer to precisely adjust exposure duration to the amount needed for a scene. The front ring is prominently labelled with numbers that represent the various stop values for simpler, consistent control over density settings. The ring has silver side knurlings for a firm grip and simple putting on and taking off. When paired with an aperture adjustment, this filter allows users of cinema or video cameras to fine-tune the depth of field while maintaining the desired frame rate.

The Variable ND offers True Color that avoids colour shift seen in other Variable filters. The NiSi True Color ND-VARIO Pro Nano 1-5stops Variable ND is made from high-definition optical glass for the best resolution and quality. The glass is coated using the NiSi Nano coating providing a waterproof, oil-proof and anti-reflective coating to avoid ghosting and reflections. The filter ring is made from high-quality aluminium creating a very light and strong filter.

We recommend focal lengths of 35mm and longer with our variable ND range.
