Whats this on Nikkor

well it wasn't moving so had a wee look inside and its not connected to anything just a little raised stud, I wonder if its just to to locate the top of the lens before its turned to attach.

My 50/1.8 Series E has a stud like that which is exactly vertical when the lens is aligned for inserting into the mount. Seems a plausible explanation for mounting lenses in the dark or without having to look?

+1 - Ronnie is the first with the correct answer and wins the prize.

The chrome ring around the waist of classic Nikkor F-mount lenses is always a non-rotating portion of the barrel and it's always the recommended portion to grip when mounting and unmounting a lens. Any "button" on such is an orientation mark.
 
You're of course right guys. This is a long time since my 3.5/35-70 Ai-S and 3.5-5.6/35-105 Ai-S Zoom Nikkors have been sold out. But both had something which needed to be pushed for close-up.

I think you'll find I should get the prize;)
So it must be an E series thing.
Cheers.
 
Yes, it is a feature of all Series E Mark II lenses and the 1986 Nikkor 50mm /1.8 AIS which was based on the Series E Mark II 50mm /1.8.
