The technical details behind this filter
ProMaster Variable ND HGX Prime (1.3 - 8 stops) 77mm Filter offers a clear sharp image and is easy to use. ProMaster HGX Prime VND filter mounts to lenses with 77mm threads and delivers an exposure reduction of 1.3 to 8 stops (ND2.5-ND256 equivalent). It darkens the entire image enabling slower shutter speeds and/or wider apertures with applications for both still photography and videography. The mechanical "hard" stops at each end of the filter's range prevent bypassing the minimum or maximum useable density. A small, knurled knob offers a tactile experience making it easier to rotate the filter quickly and smoothly, simply by touch.
