The main goal of the UV filter is to remove bluish breathing during outdoor photography, but it also effectively protects the sensitive lens surface of the lens and minimizes surface reflections.
The Polaroid UV filter is a great tool especially for outdoor photography. It absorbs ultraviolet radiation and reduces the bluish tinge of daylight, giving the image optimum colours. The multilayer surface reduces surface reflections, preserves neutral colours and light transmission. The UV filter does not affect colour or contrast changes, so you can combine it with other filters.
The filter also serves as effective lens protection against adverse effects that could damage the surface of the lens. The filter prevents dust, moisture, and water drops from entering the lens, and provides extra protection in situations where something could scratch the sensitive surface of the lens. The filter ring is made of solid aluminium alloy with expansion resistance at temperature changes.
