See Chip, saved you the trouble of replying).
The 28-70/2.8 L does certainly not have the same solid feel as e.g. the 80-200/2.8 L. It has a little play in the lens barrel (at least my sample), although not as much as my 28-135. Now, if you actually check out the resolution specs, it seems really not overly impressive. Well, to compare mid range apertures is a little like, hmmm, comparing a VW and a Ferrari at 50 mph. The interesting thing is, the 28-70 is quite good at apertures that mean wide open with the 28-135. And even at f/2.8 it's not really a bad performer. Then, there are those things you won't see when you are in a hurry: Real world results. I'll put my flame proof suit on, I have to state I believe to see a difference beyond sharpness. Maybe it's the more vibrant colors or the infamous Leica glow, the pictures appear to look different when compared to my 28-135 or 28-105 (or my Sigma 28-70/2.8).
