Unfortunately, not the elusive ED lens head. The package comes with the excellent AU-1 focusing adapter though.
The asking price is way overinflated. Although the 1200 mm lenses are scarce, they aren't that valuable even as collector's items.
I have the 1200/11 ED-IF and it is a great performer. Probably the ED lens head version is equally well behaving. The very rare 800/8 ED lens head is far superior to the 800/8 ED-IF, so there are no easy way to predict the performance of these oldies apart for actual testing them.
