Nauticam Ultra Viewfinder 180 x 1.0. Used twice. No noticeable scratches. The cap for the viewfinder (eyepiece) side is missing, but it comes with a soft storage case, a cap for the housing attachment side, and the instruction manual. I used it with a mirrorless camera housing (xt4) that was not full-frame, so if you want to use it for full-frame, you need to replace the attachment on the housing side. I will also include the parts for conversion to full-frame. The conversion is a paid service by the manufacturer (as stated on the fisheye product page), so please contact the manufacturer. If you have any questions about the conversion, please contact the manufacturer.
