Zeis Otus 85mm f/1.4 Canon ZE mount
This lens produces unbelievable sharp images with milky bokah.
This is a manual focus lens in case you did not know...
If you want the best glass this is it.
The lens also comes with a B+W 86mm XS=PRO UV Haze Nano filter paid $125.99 (FREE to you)
Paid $4400 brand new in July. Selling $3700 OBO. That is a $800+ discount for a barely used lens...This lens is as close to NEW you can get other than opening a sealed box.
