Since light reflected from non-metallic surfaces polarises, the Hoya 72mm HD MkII Circular Polariser Filter makes it possible to control which light enters the lens, giving you more creative avenues to improve your image.
One such avenue is the reduction of reflections, for example, on water surfaces. With the HOYA HD Mk II CIR-PL, you can greatly control and remove reflections, allowing you to show the natural colours and details of submerged objects.
