This is the tripod collar ring for the NIKKOR Z 180-600. The reason for the "as-is" condition is that the 1/4 inch female thread is stripped. It can be used without any problems if you only use the 3/8 inch thread. It has been used for about a year, so there are some minor scratches. Please understand that this is a used item in "as-is" condition, and purchase with the understanding that no returns or refunds are accepted. - Model: NIKKOR Z 180-600 mm - Color: Black - Type: Lens Mount Ring - Material: Metal
