For a clearer view of things The circular polarisation filter eliminates undesirable reflections from shiny surfaces like water or glass and helps to enhance colour contrasts. The universal polarisation filter is supplied complete with a 180° swing-out mount that allows it to be positioned in front of the viewfinder window to control and assess the effect of polarisation on the subject before exposure. Thanks to a range of adapters, it can be used in combination with a multitude of different lenses. Filter available in sizes: E52 to E95 Universal Adapter-M available in sizes: E39 to E49
