Okay, for you Oly camera owners who use Lumix lenses, how do you deal with the fact that the Lumix lenses aren't optically corrected for CA (chromatic aberration) in-lens, but rely on the Panasonic u4/3 body doing the final software correction of CA to the RAW file? Do you apply CA correction manually in the RAW files from your Oly during post? Is it a problem for you not to correct for CA at all? From my experience and what I've read, the CA from the otherwise fine Lumix lenses is noticable in a file unless it's been corrected. This was one of the objections to the Lumix lenses early on in the life-cycle of u4/3, that the lenses, when optically tested independant of the camera body, appeared to be poorly corrected, as they were designed to operate within the context of a camera system where the final optical correction is done in software.
From being a Lumix G1 owner, I love those Lumix lenses when the camera system automatically applies the CA correction to the RAW file, but can't see how you could enjoy doing that manually on an Oly body, with every image, in post. Maybe I'm lazy. Feel free to correct me.

PS: I read a lot of posts by newcomers to the u4/3 system via the OM-D, who are tantalized by the Lumix 14 and 20mm lenses, for instance, but don't seem to be aware that these lenses aren't corrected for CA on Olympus camera bodies. Unless there's some attempt at educating them, there will be some very disappointed folks.
