So the iS-series cameras with ED glass (1/2/3 in the U.S., 1000/2000/3000
elsewhere) should be better able to control chromatic aberration? Hmm...
I'll have to take a closer look at photos taken with my mom's iS-2. I can
think of several taken this summer that should demonstrate that kind of
optical error if the lens is prone to.
Olympus never produced any ED glass for the OM line? I must have misread
the info I read somewhere on the web

Hi C.H.Ling,
Your pictures are perfect for showing this type
of chromatic aberration. This is normal because this
isn´t a fluorite special glass and you cannot solve this
problem with coatting or making groups of elements.
I think that everybody has this problem, and Olympus gave
us a terribly heavy solution. Zuiko 180/2
Of course that other Zuiko lenses should have this
problems, even my CAMEDIA that takes a very high quality
zoom lens has this problem, due to the lack of ED glass.
Olympus with the new 35-140 f2-2,4 will be again in the
first line!!!
Finally I´m with you that you won´t reduce chromatic
aberration, stopping down. Never!!!
Dave
