L lens just for the 5d, and it is simply that the 28-135 IS shows its
warts on full-frame.
We've become a sensitive lot since the introduction of digital direct capture.
Photographers have been putting up with all variety of lens distortions and
aberrations for years on film but now most of these issues are easily addressed
in RAW post processing. Exaggeration of fall off and edge CA is partially a
product the Bayer sensor configuration of micro-lenses over sensors, new
sensors with high fill factors will overcome some of these limitations. I'd
take a FF sensor over a cropped sensor of the same density any day and so it
seems would many other photographers given the available cash.

Rob, I think a lot of the sensitivity comes from the fact that with
film, most shots were never seen any larger than 4x6, even for pros, now
we edit from much larger (Screen-sized) shots that make any problems far
more obvious. Combine that with the issues you note and people are
getting much pickier about their glass. Cheap glass wasn't nearly as big
an issue with 4x6's and ISO 400 colour print film.
