Nikon Nikkor 85mm f/1.4 AF - REAR ELEMENT question

You asked this in the Nikon forum on Photo.net. There are some responses,
why are you wasting hundreds if not thousands of dollars to post here?

Hi everyone, I was cleaning the rear element yesterday and noticed
that when pressed slightly, it moves inwards (up to a point), then
pops back out again - almost like it was mounted on springs or
something. This is the first time I've noticed such a thing - my other
(MF) nikkors all seem to have solid-mounted rear elements. Is this a
fault or just a design feature? The lens seems to be performing fine.
Has anyone noticed a similar thing?

Cheers

Ron
