I don't remember where this lens came from, maybe it was in a free lot someone gave me. I even don't know which mount it is, it could be fixed to a Sigma mount, but infinity is at 4m. So it could be even better in it's proper mount.  Already wide open picture sharpness is fine, just a bit of softness towards the edges at F 1.8. Stopped down it's really good and very contrasty, nearly surreal. Have a look at the full resolution image at F 8 or F 16. A nice, very luminous lens.
