Thank you for viewing. This is a used Kenko camera filter PRO1D WIDE BAND Circular PL (W) 58mm, for contrast enhancement and reflection removal. It was only used a few times for experiments. ◆ Circular PL filter for adjusting light reflection and vividly expressing the colors in photos. ◆ Compatible with both digital SLR cameras and film cameras thanks to the "Wide Band 1/4λ Phase Difference Plate". ◆ Thin frame design allows use with wide-angle lenses. ◆ Knurling improves operability during attachment and detachment. ◆ Made in Japan I will sell it to someone who can use it.
