Hi Johne, 
 
I use a lot a IIIf black dial and all I can say is that I get perfect focus in a consistent way using both a Summicron 50mm f/2 and a 90mm f/4 Elmar. A great camera and a joy to photograph with (please, visit http://www.photo.net/photodb/folder?folder_id=275117, almost all the pictures there have been took with the IIIf)
 
Cheers, Ludwig Argüelles
