<<BTW, the new 80-200 AF-S has approx 1.5 stop light
loss center to corners
at 200mm at 2.8, and 1 stop light loss at 200mm at
4.0.>>

>>This is what I'd call an extreme case of light
fall-off. Fortunately, my
80-200 AF-S behaves nothing like this. In everday use,
I have made many
wide-open shots (@ 200mm) and have never noticed a
darkening of corners,
unless I have pushed the film (E200 pushed to 800).
Even then, my pictures
don't reflect the results quoted above.

Actually I bet your 80-200 AF-S does behave like this (
I tested 2 samples ), but due to the film type your
using ( probably lower contrast chrome or negative type
film ), the exposure loss in the peripheral region
hasn't caused you to find it objectionable. The film
type you mentioned ( E200? ) is most definitely a lower
contrast film unless pushed a stop or so. Whether you
notice the light loss or not doesn't mean it isn't
there, it just means you haven't been caught in a
situation where it's been problematical ( try some
velvia or provia and you might change your mind! ). Pete
