Honestly, I think that ic-racer might be the most accurate here. The marketing obsession perhaps was the main reason for so many being sold? True, they are handy, but, really, isn't the 28-80 far more handy? The 80-200 does not have all that much over the 135. That prime is: usually faster, at least as sharp (if not sharper), more manageable, less problems through wear with time.
Still, to get a perfect portrait lens in the 80 to 100 range one would have to search forever to be able to find one as cheap, and, let's face it, as good as this ubiquitous monster. I wanted to hear feelings on this lens as it is everywhere, and then some. - David Lyga
