LAOWA 12mm F2.8 Zero-D for Canon RF mount

This is a wide-angle lens with an extremely wide 12mm full-frame focal length, designed to minimize optical distortion.

Purchased in 2021 from Map Camera, I rarely used it in my environment and it has been stored in a dehumidified storage. I tested it for this listing and it works without any problems.

Compatible mount: CANON RF mount (listed as EF mount because it's not in the category list.)
