Classic SLRs Series :
In anticipation of the increased use of microelectronics in new Nikon cameras such as the FA, several design changes were made in 1981 to Nikkor lenses which do not affect the Nikon bayonet mount or the AI feature which automatically indexes the maximum aperture with the camera's metering system. Designated "AI-S type" lenses to avoid confusion with the Al-type lenses, these Nikkor and Nikon Series E lenses feature a focal length indexing ridge, a lens type signal notch, lens speed indexing post and, for ease of reference, an orange-painted maximum f-number on their aperture ring. These, however did not materialized as there was a swift change in trend at the market place.
These Nikon Series E lenses wer the first batch to go "AI-S"...
Minolta's X-700, incorporating the Minolta Program System (MPS) with three exposure control mode in Programmed, Aperture Priority AE and manual was selected as the first European Camera of the Year back in 1981 - Nikon replied with their first multimode SLR in the ultra-compact Nikon FG which for the first time, incorporated with a Programmed Mode in a Nikon SLR body. All you need to do was to turn the aperture ring to the minimum aperture value of your Nikkor lens to operate in this mode, the FA - however, added a layer on top of the program automation with shutter priority AE. Nikon claimed FA's performance may suffer with the use of non-Nikkor and non-Nikon Series E lenses in conjunction with the Nikon FA - To be fair, which is not totally true. With an AI-S lens type, because of the focal length indexing ridge, lens type signal notch, lens speed indexing post and automatic maximum aperture index (Al) system, the FA may operate at its most convenience point, especially in the Dual-Program Mode (in which FA automatically selects either Normal Program or High-Speed Program depending on the focal length of the AI-S type lens in use) and the Shutter Priority Mode (in which the aperture is precisely controlled and accurately stopped down to the metered f-stop position). In conjunction with the FA's introduction, Nikon Teleconverters have also been modified for use with Al-S type lenses. These new Teleconverters are TC-14A, TC14B, TC14C, TC-201 and TC-301.
The Pentax drew the first blood by introducing a ME-F camera in 1982 with an 35-70mm f2.8 autofocus lens and raised the curtain for the era of autofocus SLRs. The autofocus camera, was not too popular yet until 3 years later when Minolta brought the Maxxum class of autofocus bodies in 1985 with the world's first body-integrated AF SLR system. What does these development signifies ? Barely a year or two after the FA was launched, Nikon could have realized the future was not at "multimode" but at the autofocus. The development and implementation of the AI-S lenses within the Nikon system was a waste - but not the concept, as all the autofocus Nikkor lenses are AI-S in nature. These lenses can be used on the FA in manual mode and yet enjoy the full benefits as an AI-S lens and take advantage of what the FA has to offer in full fletch features and capabilities.
The AI-S lenses could had been intended to convert the future Nikon bodies to go multimodes in general - which is Nikon's apparent weaknesses in the market place during that period. In many ways, it is a definite faster lens type (with shorter focusing or broader turns - depends on focal length of the lenses), but may not interpret into more superior construction quality than the AI lenses. The Dual-Program Mode is an additional considerate feature, but it is not an neccessity as the FA cannot sense the the focal length of the lens in use, normal program is the default program - other system still perform (As long as it is a minimum AI-Spec lens). It is lighter, the traditional chrome ring has been substituted with aluminium. Most of the optical formula remained unchanged (Given the same maximum aperture of the lens), while newer and faster Nikkor lenses were introduced and there was no basis to compared (Oh.. I think Nikon's speed of converting the AI-S lenses from AI is few times faster than the process of upgrade and replacing the AF Nikkor with AF-D designation).
More interestingly, the F mount on the camera body has additional lever and pin to establish communication between lenses and body. This is a clear departure from the simple Aperture Stopped Down Lever for Automatic Indexing operation found in any of the Nikon camera bodies. You may referred to the Various F Mount for further reference to see how individual lever and button works between the lens and the body (Especially the section covering the "Signal Pins and Levers on the Nikon FA's Lens Mounting Flange".
Anyway, there are no significant advantage for you to 'upgrade' the AI lenses to AI-S directly, and if you are one of those many AF users and want to get a manual focus body as back up - ALL your current AF Nikkor lenses will fit and work well just as an AI-S lenses on the FA. As long as your lens is not a Non-AI Nikkor lens or if you have already did a AI-modification, it will work in the FA with some compromises. Warning: Non-AI lenses are not recommendated to use with the FA. After modification, the AMP (Matrix metering) is still not workable, instead, center weighted metering will be the default metering system. Which means to say, the FA's optimum lens-to-use is minimum a AI-spec Lens.

Sounds complicated ? No. In fact, as far as manual focus Nikon cameras are concerned - It began from 1982's FM2 onwards (With the exception of the F3 and its variations - 1979's EM was the first, FG was the second), the FE2, FM2n, FA, FG20 (1984), F301 (1985), the current light-weighted versions of FM-10 and FE-10 need a minimum specification of an AI lens to work properly. In fact, it may damage the meter coupling mechanism if force it on to use on any of these bodies mentioned.
