Cokin Z-Pro Expert Filter Kit U3H4-22

The Expert kit for Large 100mm size is composed of a GND4 (2 f.stops) a GND8 (3 f.stops) a full ND4 (2 f.stops) and a microfiber. Graduated Neutral Density (GND) Filters allow to reduce the amount of light reaching the sensor so that you can reduce shutter speed and get some motion effect. By rotating the filter-holder you can place its effect, by sliding it up and down you can setup its intensity so that you can balance your exposure correctly. It also includes 4 adaptor rings (67,72,77 and 82mm) and a Filter-Holder.
