I don't know whether there is or not.

The minimum aperture is orange on the AI-S, all
of the aperture numbers are white on the AI.
There's also a semi-circular cutout on the AI-S
lens mount just above the notch for the camera's
locking pin.

Yeah, I shot with one of those for years.
It's a decent lens: nice and sharp with very
little distortion, but it flares badly. I got
some really good black-and-white pictures with
it using an dark yellow or light orange filter,
but color images were always a bit disappointing.
The lens just didn't have enough contrast for my
taste.
