The Zeta Quint C-PL is a circular polarizing filter that suppresses unwanted light reflections, vividly reproducing the original colors of the subject. It can reduce reflections on water surfaces and glass surfaces, and provides a color contrast effect that deepens the blue of the sky. By adopting a high-transmission polarizing film, it achieves a light transmission of approximately 1EV brighter than a standard C-PL filter. Features: * Reinforced glass for peace of mind * Duralumin frame * Dust-free coating that resists dirt * ZR coating that achieves ultra-low reflection * Black ink treatment on the outer periphery of the glass to prevent internal reflection * Rotating frame structure for easy attachment and removal * Thin frame design compatible with wide-angle lenses * Lens cap and hood can be attached * Knurling for improved operability * Matte black anodized finish * Dedicated filter case There is a tear near the lid of the box, but the contents are not affected.
