SmallRig 4216 MagEase magnetic CPL filter kit (52mm)

The SmallRig 4216 MagEase 52mm circular polarising filter reduces reflections from non-metallic surfaces, including lakes, windows, waterfalls, glass and building surfaces. It increases colour saturation for bluer skies and clearer-looking water. Rotating the filter adjusts reflection reduction, and it can also act as an ND filter by reducing light by 1-2 stops.

The filter uses German Schott B270i HD glass and an ultra-thin CNC-machined aluminium alloy frame that avoids vignetting even with ultra-wide-angle lenses. Its AR coatings resist water, stains, mould and scratches while reducing colour cast. It attaches magnetically to a SmallRig 52mm magnetic filter adapter ring.
