The illustrations in black and white are much clearer and easier.



Original AI-S lenses have their minimum aperture value (largest number) on both the aperture ring and ADR ring in orange.
An original AI or pre-AI lens usually has the minimum aperture (largest number) on the aperture ring in blue (does not always apply). But no doubt, the ADR value is not color coded.

AI Modified.jpg

AI and AI-S lenses have a lens speed indexing post (lug) that is required for matrix metering in FA or F4.
An AI-modified Nikkor will not have such post and thus it will not work with matrix metering. The same applies to non-AI lenses when used with Nikon F4.

Non AI.jpg

ALL AI or AI-modified lenses have a meter coupling shoe (rabbit ears) that has a tiny opening (hole) on each ear. The meter coupling ridge is essential for proper Automatic Indexing.
The rabbit ear is a solid piece (no holes) for non-AI Nikkor lenses. The edge of the lens is flat (no meter coupling ridge). Generally, models after 1979 - with the exception of the professional F-series models (F5 may require factory modification) cannot use these lenses. eg. FM2, FM2n, FE2, FA, FG, EM, FG20, F-301 and virtually ALL AF models.

Why there aren't any AF lenses here ?
Because I'm lazy and I have not featured any AF camera models yet.
If these illustration still can't help you to understand.
Beat me...
