This is a magnetically detachable filter. There are some minor scratches, but I don't think they will affect the photos. [Details] K&F CONCEPT 77mm Magnetic C-PL Filter + Magnetic Adapter Ring [Super easy magnetic attachment/detachment] This type can be attached and detached with magnets, so unlike general screw-in filters, the 77mm magnetic C-PL filter can be attached and detached very easily and quickly. You can change the lens filter in just one second. The exterior may be a mix of old and new, but the contents are the same. [Color contrast effect] Circular polarizing filters can be used to vividly photograph the color of the sky or to eliminate reflections on glass or water surfaces. Using a PL filter removes surface reflections, allowing the original colors of objects to be reproduced more vividly. [Photograph in original colors] The lens filter uses double-sided polishing technology, allowing you to photograph in the original colors even when using a telephoto lens. Premium high-definition optical glass is used, providing water resistance, dust resistance, stain resistance, and scratch resistance. [Ultra-thin & multi-layer coating] The outer frame has an ultra-thin design, so there is no need to worry about vignetting even with a wide-angle lens. It uses 28-layer coating to achieve high transmittance. It significantly reduces lens flare and ghosting, suppresses reflections, and allows you to take bright and colorful photos. [Filter set] 1 × Magnetic CPL Filter + 1 × Magnetic Adapter Ring. The filter set includes a magnetic adapter ring for easy attachment of other K&F CONCEPT magnetic filters.
