HD Coating

HD coating is the term used to describe several special layers applied to the filter glass. Their main purpose is to ensure that as much light as possible passes through the glass without any loss. This prevents the image from darkening and preserves its original colors. At the same time, these coatings significantly reduce unwanted glare and light veiling, which can appear in the image when shooting into the sun, for example. They often have protective properties as well—they increase the filter’s resistance to scratches and make cleaning easier by repelling water and grease. The “HD” designation refers to high optical quality, which does not affect the sharpness of details in photos taken with modern high-resolution cameras.
