I 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 of a klutz and had immediately picked up a K&F UV filter for my lens as damage protection. It has modestly helped for removing haze in SF Bay landscape shots but has added some ghosting to low-light shots (common to UV filters) and is mostly unnecessary in modern digital camera... As I mentioned, I keep it on to protect my expensive lens.

As soon as I saw this CPL I ordered it so that I can swap between them, depending on the situation. If I'm shooting at/around water, or at/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 not noticed any added distortion to color or clarity.

As for fitment/build quality it feels very premium for the price point. It doesn't bend or flex when I don't thread it just right, so I haven't mis-threaded it after 10-15 installs. The hydrophobic properties are good, too - I got caught off guard by a sprinkler and the filter shed all but a couple tiny beads of water that easily came off with a microfiber cloth in one swipe.
