New technologies - are what makes the production cheaper and allows to produce better products FOR THE SAME MONEY.
This is just true if you build an *old* product with *new* technologies. But the 24-70II is a new calculated lens, with 2 more glasses and other specs. You have to pay for the development, for the ingeneers and for the new expensive ULD elements et cetera. The price rises fast if you come to the limit, see @OTUS/Zeiss.
My point was that the old product can be bought for a lower price, too, after the new one came to the market. So, *if* you want the latest you have to pay for it. If not, everyone can get along with the old one. An old one, matured for years and known for the best press photos shoot everyday. Better than most of us, maybe.
