Speaking of the 80-200mm AF-S. This lens has undergone quite a number of changes in the recent years hasn't it?
At some point it was a push-pull 80-200mm AF, then replaced by a two-touch 80-200mm AF and finally the 80-200mm AF-S that was discontinued just a year ago, correct? And now it's back to the two-touch 80-200mm AF. So, the loaded question: how have the optics changed from year to year through all these hardware/housing/motor changes? What model/generation would you recommend getting on the used market given the recent AF-S prices are above what the new/current AF version sells for?
