Oh, and Don, I think you are right. Most MF lenses back in the day, even less expensive models, had a longer and more precise focus turn. Every once in a while I see it referenced on a high end AF lens in a review, but I know the lenses I own don't have that same precise feel.
In fact, modern MF lenses also have a longer 'throw' in the focus ring as do my Samyang 14mm and Voightlander 40mm (both are EF mount).
