Kenko PRO1 D Pro ND4. Wide Ultra-thin frame type Pro ND4 is a highly accurate filter with extremely high neutrality. It adjusts the amount of light by 2 f-stops without affecting the colors. For 77mm lenses. By using step-up rings such as 72-77mm, it can also be used with smaller diameter lenses. (Larger can be used for smaller!) Used several times in streams, etc. (No water damage) I re-cleaned the lens and checked, but it is completely undamaged. Due to the manufacturer's package renewal, the product package is old, but the contents are the same as the manufacturer's current product. Please understand that this is a used item and no claims or returns are accepted. For those who prioritize the contents over the old package! I will reply to comments and ship the product as soon as possible. Thank you for viewing.
