I think there's some confusion in regard to CA vs. digital fringing. I've experienced quite a bit of the latter with FA, K and A lenses. This condition is typified by color fringing (usually cyan or red) at the edges of dark objects that intersect with extremely bright highlights, such as a sky. I've found it's much less of a problem with DA lenses. It can be cured by cloning or a "replace color" operation. But it's somewhat of a pain in the butt. Paul On Sep 3, 2006, at 8:33 PM, P. J.
