Someone asked me what the notch in the focus ring on early Nikkor AF is used for?
As the big internet doesn’t have a quick answer I want to see if Nikongear with all the knowledge can give an answer.

No, actually the notch is only on early AF lenses, not seen before or after.
It can be seen on this page

Uuuh, sorry. I did not read properly. I do not know about that one.
Will eliminate the post above.

My wild guess is that the notch might be for the dedicated wrench to screw the focus ring off the internal barrel?

i knew the reason but i forgot :o :o :o
these are usually present on the plastic focusing rings ::)
