Sony Zeiss FE 16-35mm F4 ZA OSS lens. Vario-Tessar T*. Full Frame. E-mount.
This beautiful lens is in great condition, as you can see from the photos. I've always used a Hoya Pro1 Digital 72mm lens protector, which is why the glass is in top condition. No marks on the body (again, because I take care of my lenses).
