1 out of 10 points and not recommendednonenone
I got a lemon. Fortunately I could return.reviewed April 20th, 2009 (purchased for $500)
Terrible CA at any aperture, three branches outside my house would just be purple blobs.
Moderately soft until stopped down to f/5.6.
Back focus where 3ft becomes 7ft.
Never buy this lens on eBay. Make sure you can return it if your copy is a lemon.
