1. AFS is speed is faster than screw driven AF.
2. VR will allow 3stops slower speed than 1/focal length. The analogy is at f5.6 with 3 stops slower is similar to shoot at f2.8 with faster speed handheld. The trade off is the slower speed will be a disadvantage for action shoots.
3. ED glass is better than normal glass due to low dispersion property.
Those point facts are technology not gimmick!
I knew someone in CS upgrade from AIS to AFS, if AIS still can serve him better why bother upgrade to AFS and spend more money. Technology also a selling point and of course ease of use.
If person want the best optics then go for pro classes f2.8 lenses, no need argument about it. The consumer lenses always have to compromise due to its price.
Technology when used properly is beneficial, otherwise it's not. The pro people upgrade from AI-S to AF to AF-S because it helps them get the job done in a better way, not because it will make their output better. If you are already very good with AI-S, then AF-S will give you a bit more edge. If you can't even hold a lens properly, then no AF-S, VR, ED, IF, DO, USM, is going to help. And putting technology onto a piece of mediocre lens isn't helping much. It's just like putting a $20k car radio into a cheap car, it ain't going to drive better. Or putting a $20k speaker system at the end of a mini compo. It ain't going to sound better.
Best optics doesn't necessarily come from the pro f/2.8 zooms. The primes give the best optical quality. Most of Nikon's prime lenses below 105mm doesn't even have the ED, VR and AF-S nomemclature on it. Yet they are the best optically.
Consumer zooms don't necessarily have to compromise in quality. The no-frills 28-105 f/3.5-4.5, 28-85 f/3.5-4.5 are both very very good performers. In fact the older 28-85 is supposedly even better optically.
Even for the pro zooms. AF-S is not necessarily better. The old AF 20-35/2.8 is optically better than the newer, more expensive AF-S 17-35/2.8 ED-IF. And the comparitively cheaper AF 35-70/2.8 is no slouch compared to the AF-S 28-70/2.8ED-IF either.
Don't lust after technology. Work on your technique, and you can get good pictures even without all those frills.
