Hello. i have a couple of questions...
1: what is the official name of that ring with the aperture tab?
2: does the aperture tab ring come off after you unscrew and remove the bayonet?
3: is the removal steps the same for most of not all Nikon cameras (modern, D200+)
4: what material is this usually made of?
thank you very much. i have a project that i cannot disclose at the moment but i will share it with you as soon as im done with a prototype. Thanks!

Aperture follower.
Yes pops off when you undue the mount,,,
Recalibration in needed,,, in priciple,,,
Same design more or less for all and suspect to become stuck or slow returning, a common issue and Nikon professional service is avare of this and will fix it for free in my experience,,,

For reference, the part that is on the lens/aperture ring, that turn this 'aperture follower' is called 'Meter coupling ridge'
Tells the camera what aperture is selected Ai, Ais, AF, AF-D, 'old' AFS etc,,, but not G and E type

Thanks! Aperture follow...what a name :o :o :o
hmmmm...the one on my D7000 is hollow underneath. and i think is made of plastic. other than that i dont remember seeing another one since i usually leave these on the front plate with the bayonet mount. but i hope that it's solid.
there seem to be some grooves under it, could this be where the calibration is supposed to be done?
thanks, nice to know.

The grooves/cut outs in the camera mount are for the ring with three blades or 'springs', the ones that holds the lens firmly onto the camera mount.
