Thank you for viewing. This is a CPL filter made by Marumi. The filter diameter is 67mm. It is a multi-coated CPL filter with a thin frame and inner frame coating to minimize the impact on image quality. I am selling it because I have replaced it due to an increase in lenses with larger filter diameters. Although there are no noticeable scratches or coating peeling, there are some wiping marks due to use that do not affect actual use. Please see the images for details. If you have any questions or need additional images, please feel free to comment. #MARUMI #Marumi #Marumi Optical #Filter #PL #CPL #PL Filter #CPL Filter #67mm #Φ67
