Enjoy versatility with minimal color shift by adding a 67mm True Color ND-VARIO Pro Nano Variable Neutral Density Filter from NiSi to your kit. These filters are designed to reduce exposure while maintaining "True Color" with minimal color shift. Plus, their 1-5 stop ND range has hard stops at each end that will ensure you do not see the "X" effect in your images. Being able to seamlessly adjust exposure will ensure you are capturing images at their best quality.
The filter has some other features that will improve performance and usability. There is a 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. And, the 72mm front filter thread is larger than the rear thread to reduce the change of vignetting on wide-angle lenses. It is recommended that this filter is used on 35mm or longer focal lengths.
