Thats a relief. For a moment yday I did wonder if this was one of those hoo-doo
"reverse-macro", kind of "fixed" version of the original lens! :-)

I wonder why this counter-intuitive behaviour though...

I havent tried filters but the hood when fitted in backwards is extremely tight.
Ill try cleaning it up a bit today. Will vaseline or machine oil hurt?

Thats the first time I am hearing that an Olympus lens would have CA! Hmmm...
did not know of it. I use lightroom, are there any links to profiles that I can
download
for 11-22. I definitely dont want to be making one.

What is the best way to reproduce CA effect using 11-22mm? What setting for E30?

Thanks,
