Mei-Sho Optical (Meisho Kogaku) TTArtisan 21mm F1.5 ASPH for Nikon Z mount. Please note that this lens is for the Nikon Z mount. There are some scratches on the edge of the hood for attaching external filters, but otherwise it is in beautiful condition. (See photo 2 for a better understanding) The inside of the lens is also clean with no haze. My personal impression of the image quality is that it is soft at the maximum aperture, but becomes sharper from around F2.8. Everything in the photos is included.
