Well as long as this is going on...

Nikkor 70-300/4.5-5.6 G AF with 13 elements in 9 groups, 2.9" dia. x  
4.6",  no AFS motor, no VR, 1.03 lbs, $125.
Nikkor 70-300/4.5-5.6 G with 17 elements in 12 groups, 3.1"dia. x  
5.6", built in AFS motor, VR, 1.6 lbs, $480.
Nikkor 70-300/4.0-5.6  ED with 13 elements in 9 groups, 2.9" dia. x  
4.9", no AFS motor, no VR, 1.14 lbs, $295.


Not much of a hit at all in the weight department for much better  
focusing, and VR and 4 additional lens elements providing,  
presumably, better correction.
