B+W magicpol GRÜN Green Colour Polarizer (55mm) format_Four Thirds which helps keep the weightThis B+W magicpol GRN filter for 55mm filter threads is a unique colour polarizer that shifts from light green to dark green. To achieve this effect, a polarizing filter should be mounted in front of the magicpol filter; the effect is then achieved by rotating the polarizer (polarizing filter not included).
