Enjoy finer exposure control with minimal color shift by adding a 67mm True Color ND-VARIO Pro Nano Variable ND Filter from NiSi to your kit. These filters are designed to reduce exposure while maintaining "True Color" with minimal color shift. Their 1- to 5-stop ND range has hard stops at each end that will ensure the "X" effect will not appear in your images. Being able to seamlessly adjust exposure will ensure the images are being captured at their best quality.
The filter is made of high-definition optical glass and features NiSi Nano coating that offers anti-reflective properties to reduce flare and ghosting. Also, the filter is water- and oil-resistant to make it easy to clean and shoot in inclement weather. The lens comes with a removable rotating lever for easier operation. The larger, 72mm front filter thread allows an additional filter to be stacked on front of this filter with only a minimal chance of vignetting when used with wide-angle lenses. It is recommended that this filter be used on 35mm (full-frame equivalent, 28mm for APS-C) or longer focal length lenses.
