Introducing Kenko's Circular PL Filter (67mm)! It seems that with AF single-lens reflex cameras that have a half mirror built-in, general PL filters can cause errors in exposure and distance. A circular PL filter, which is a type of circular polarization filter, is recommended. There are no scratches or scuffs. The coating is also not peeled off. The case is not clean. There are scuffs, scratches, and cracks. I bought it 7 years ago, and I took landscape photos after purchasing it. You can adjust the contrast to your preferred color tone by turning the filter's rotating link. I've only used it once, so it's almost unused. I kept it in my camera bag thinking I would use it someday, so the case is not clean. Please consider this if you are concerned about it. The filter is clean! The polarization effect is perfect! You can freely change the color tones when you are concerned about reflections and glare during shooting, or when you want to make the contrast crisp.
