This lens is the sharpest lens I have ever used, and gives beautiful bokeh! Glass is immaculate.. dots seen in photo's are dust particles on UV filter. Comes with UV filter (on since day 1) and is in Mint ++ condition- with box. This lens is also very much at home with mirrorless cameras with Nikon 4/3rds adapter, such as Panasonic and Olympus.
