NiSi 77mm True Color ND-VARIO Pro Nano 1-5stops Variable ND

NiSi 77mm True Color ND-VARIO Pro Nano 1-5stops Variable ND from NiSi is a professional-grade product. The NiSi True Color ND-VARIO Pro Nano 1-5stops Variable ND is designed to mount onto lenses with 77mm front filter threads and provides an exposure reduction of 1 to 5 stops. The 0.3 to 1.5 density creates a darkening of the entire image, allowing wider apertures or slower shutter speeds than usually possible. The degree of density is easily controlled by rotating the front filter ring with or without the included silver lever, helping you predetermine the additional exposure length required.
