This is an 82mm H&Y EVO Rich Tone Natural CPL magnetic filter. It's a C-PL filter with the equivalent of a 1/16 white mist filter. Purchased from Amazon around July 2023. The edge of the filter has a crack, so I'm selling it to replace it. When used with an RF 15-35mm lens at around 18mm, the cracked area appears white in the corners of the frame. Originally, when using it magnetically, there was vignetting in the corners of the lens at wide angles, so I didn't use it at those focal lengths, but it's still bothersome! It probably won't have much effect if used at 24mm or longer, or if used with a screw-in mount. Retail price: 19,800 yen Here's the manufacturer's product description: It controls contrast without color cast and has the effect of a 1/16 white promist filter. It's characterized by its ability to reduce contrast in scenes with harsh contrast during daytime shooting while adding a gentle mist effect to the highlights. Kazuya Seki (Photographer) This product combines a subtle soft effect equivalent to a 1/16 white promist filter with a latest-generation polarizing film that eliminates color cast. It's the second product produced by photographer Kazuya Seki, following the 2024 cinematic CPL filter. While using the CPL filter's effect to remove and enhance reflections, it also adds a touch of soft effect from the White Promist filter. In portraits, it adjusts reflections on hair and skin, as well as on foreground/background scenery, plants, floors, and walls. In landscapes, it slightly reduces the overall contrast while adjusting reflections and color contrast on rock surfaces, trees, and water surfaces.
