Thank you for your interest. This is a 77mm variable ND filter from Marumi. I used it for a while, but I'm selling it because I've changed the filter size. There are some scratches due to the ND filter, but there's no problem with taking pictures. It costs over 30,000 yen when new, so I'm offering it at a lower price. I hope you'll consider it. Please feel free to ask if you'd like me to add more photos. Thank you. - Model: CREATION Variable ND2.5-ND256/V - ND Range: ND2.5 (0.4) to ND256 (2.4) - Light Reduction Stops: 1.3 to 8 stops - Size: 77mm Thank you for looking.
