The glass & exterior of this lens is in superb condition. I have the Otus 28mm, 55, & 85 and they are all industry leading sharp and have the Zeiss superb contrast even in very small details. They are virtually artifact free and suffer a near complete absence of chromatic aberration, even in the corners. Speaking of the corners, the lens is razor sharp corner to corner. Focusing the lens is a joy, very precise and the rotation has a buttery feel. The only thing of note with this 28mm is the lens shade is a bit stiff but it still mounts & unmounts just fine. Manual focus and is the Canon EF mount. $3,000
