Probably the most useful filter in a photographer's gadget bag. A circular polariser filter can eliminate or enhance reflections, saturate colours and help combat haze. Adjust the effect of the filter by turning the outer ring. The effect of a circular polarising filter is one of a few effects that cannot be simulated using computer software. The effect is at its most noticeable when shooting at 90 degrees to the sun. Be wary of rogue traders offering cheaper linear polarisers at knock down prices! A linear polariser does not function correctly with the autofocus systems of modern cameras. We only sell top quality circular polariser filters.
