> One more thing, why don't Olympus provide those data?
I don't think I've ever seen any lens manufacturer publish
resolution tests for various apertures.
Besides, too many factors or ways to interpret the information.
And, these tests are only valid for a given reproduction ratio.
Focus on an object at infinity and see things alter a little
bit. Macro or near macro performance differs too. These test
pictures were all taken from a size/distance that would be used
for a tightly framed "head shot".
This was a quick-and-dirty test that I did to get my arms around
the basic comparision of the old Zuikos on the E-1.
