This is an L-bracket made by SmallRig for Nikon Z series mirrorless cameras. Compatible with Z5, 6, 6II, 7, and 7II. I am selling it because I recently purchased a Z5II. I also use the same bracket on my Z6II. It is Arca-Swiss compatible, effectively protects the bottom of the camera body, and was advantageous for the trade-in value of my Z5. Used for about a year and a half, with no noticeable scratches.
