The Calumet CPL filter is a circular polarizing filter for camera lenses. It reduces reflections on non-metallic surfaces, such as water and leaves, and enhances color contrast and saturation. The AGC glass has a light transmittance of over 99% and a hardness rating of 6H, with 28 coating layers distributed across both sides.
The hydrophobic and oleophobic coating reduces the adhesion of water, grease, and dirt. The aerospace-grade aluminum frame has double threading, allowing two filters or accessories to be used simultaneously. The filter is suitable for portraits, landscapes, street photography, and video.
