Hoya HD2 Circular Polarizer 37mm

overview

Light rays which are reflected by any surface become polarized and polarizing filters are used to select which light rays enter your camera lens.

• They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.

• They also saturate colors and increase contrast.

•Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; Circular polarizers are designed for today's newer split-beam metering systems used in auto focus cameras. Check your camera's manual.
