I have owned this amazing lens for around 5 years, and can honestly say it is the sharpest lens I'm have ever owned.  I have owned many lenses from many brands over the last 50 years, but the performance of this lens is astounding.
Colour rendition, sharpness and resolution are all off the scale . It’s condition,is immaculate in and out.
When I,have used it for portraits, it has proved to be brutally sharp showing every pore and blemish. That’s how sharp,it is.
Focuses down to life size so if you are into macro photography, this is beyond reproach.
Comes with original hood and box.
If you are looking for one of these amazing lenses, this particular example deserves your most serious consideration.
Good luck
