A NiSi 67mm True Colour ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter will give you more precise exposure control with less colour shift. These filters minimise colour shift and preserve "True Colour" even under extreme exposure conditions. With hard stops at either end of their 1 to 5-stop ND range, you can be sure your photos won't have the "X" effect. The finest possible quality of images will be captured if exposure can be easily changed.

The filter has an anti-reflective NiSi Nano coating that helps to lessen flare and ghosting. It is constructed of high-definition optical glass. In addition, the filter can withstand oil and water, making it simple to shoot and clean in bad weather. For simpler use, the lens has a detachable rotating lever. When used with wide-angle lenses, the larger 72mm front filter thread of this filter makes it possible to stack an additional filter in front of it with very little risk of vignetting. Using this filter with longer focal length lenses, such as 28mm for APS-C or 35mm (full-frame equivalent), is advised.
