Working with lenses, and evaluating lens quality and performance can be, on the one hand, one of the easier things in photography to quantify. Optics is a well-understood science, there have been few breakthrough developments in lens construction since as far back as the 1950s. It’s been said that there have really been no discoveries in optical science since the ‘20s, in fact- although the introduction of metallic multi-coatings and glass formulae have certainly come a long way since the ‘60s. Getting performance numbers for lenses is almost as straightforward as hooking up a race-car to a dynamometer. The results are pretty much irrefutable. 

Well, I'm just a little underwhelmed by CES.  Although I would have liked to see Lady Gaga (she doesn't return my calls anymore... ) there's been just little or no real earth-shattering news coming out for the pro photographer.  Here's the new improved workhorse of a lens from Canon, though, the2nd gen.
