Hoya 37mm UX II PL-CIR Filter

Unlike other Circular Polarizing filters, the 37mm Hoya UX II CIR PL Filter is not for cutting reflections but instead to help control light reflections from non metallic surfaces. It also enhances the saturation of tree leaves and skies, increasing the image contrast. Compatible with digital and film cameras, the threads on its edges allow the installation of other filters and a lens cap on it.
