recently got my first modern digital camera, a Canon R50 with a kit lens, along with an RF 24-240 lens. I'm a bit clumsy and had immediately picked up a K&F UV filter for my lens as damage protection. It helped modestly to remove haze in landscape shots in SF Bay, but added some ghosting in low light shots (common with UV filters) and is mostly unnecessary on modern digital cameras... As I mentioned, I leave it on to protect my expensive lens. As soon as I saw this CPL, I ordered it so I can switch between them depending on the situation. When I'm shooting on/near water or on/through glass, I put this filter on to get better, clearer shots. I'm still working on my photographer's eye, but so far I've noticed no additional distortion of color or clarity. As far as the features and build quality go, it feels very high quality for the price. It doesn't bend or flex if I don't thread it correctly, so I haven't threaded it wrong even after 10-15 installations. The hydrophobic properties are good too - I got caught by a sprinkler and the filter shed all but a few tiny beads of water, which were easily removed with a swipe of a microfiber cloth.
