What I will say is that like most older designs the transition to sharpest focus is a very long smooth place making it difficult to find exact focus. I find that this is one of the issues preventing people from enjoying legacy lenses; some of them are very difficult to find exact focus. On the other hand the old FD mount L lenses snap into focus wonderfully as do the Nikon ED telephotos. http://gallery.leica-users.org/v/don_dory_gmail_com/Pink+Dogwood+20mm.jpg.html -- Don don.dory at gmail.com
