Depending what cameras and lenses you have - or want to have - these charts may be useful.
Jerry, it is my understanding that the D610 can use P lenses with an updated software.

Could be. I never bothered to figure out all the letters added to the model names of lenses.
Where's the secret decoder ring for the Nikon alphabet soup? Like AF-I vs AF-P vs AF-S vs AF vs AIs vs AF-D?? How about FX vs DX vs D vs G vs S vs E? Did I miss any letters?
The craziest thing about that first chart is all the Limited Compatibility cells and the multiple and various qualifiers. Look at their newest AF-P technology, and note all the cameras with explicit "Not Compatible" assessments. Backwards compatibility used to be Nikon's strength, but now it's Canon's.

Don’t all manufacturers have their own “code system”? I don’t think it’s limited Nikon.

You wouldn't see a chart like above for Canon EOS technology.

Yes, Canon does.
The RF mount works with EF, EF-S, RF and RFS lenses 100%.
No M lenses.
Really tough chart to follow I know, but Canon owners put up with the struggle getting through the Canon chart.

Maybe the engineers couldn’t sort it out either 🤷🏼♂️👹
AI - Aperture Indexed. These lenses usually have an aperture ring. They can Manual focus, or AF, or AF-D.
AF - screw drive autofocus
AF-D screw drive autofocus, with distance encoding
AF-S Lens motor autofocus, includes distance encoding
AF-P Lens motor autofocus, but a different type of motor (pulse)
E-type refers to the aperture control, it's electronic, not mechanical and only newer bodies support it.
G lenses do not have an aperture ring
There was a lot of effort to maintain some degree of compatibility from the original F-mount of 1959.
Canon decided to do a clean break from prior mounts when they created the EOS specification.
Which approach is better? Probably like beauty, it's in the eye of the beholder.

AI is Automatic Indexing (which really was no indexing).
Thank you, I always thought "automatic" was not an appropriate word. Yes, that is how Nikon documented the term "AI"

Before AI on a metered Nikon camera you would have to do the indexing manually by turning the aperture ring to minimum aperture then maximum aperture. This is to synchronize the internal aperture scale to that of the lens. With AI Nikon simply use the ADR (aperture direct readout) to show the aperture number on the lens in the viewfinder and thus no indexing is needed so they called it auto indexing.
Now in the era of digital cameras where all camera display aperture with the LCD and no ADR. The last camera with ADR was the F5. So to display the aperture in the viewfinder correctly (for the non CPU lenses like the AI lenses) you would have to enter the maximum aperture into the camera. So basically back to manual indexing.
