Thanks everyone for the advice. I will play around with it some more.

bobc, your original post in this thread referred to a "red edge" which seemslikely to be the same chromatic aberration that I got on my moon shot and have seen on other high contrast photos. The prevailing theory is to set the aperture opening smaller to help in this situation, as you did yourself with your great moon shot. I am still waiting for the next full moon to retry mine.Meanwhile I did do some test shots in full sun of a white post against a dark background at f8.0 and still got a "blue edge" on the post. Maybe its relative, as the contrast is extreme and the CA may be unavoidable.

I wonder if much testing has been done regarding CA and the FZ20?

I get this too in bright days taking pics where the subject is very light against a dark background, but not in all shots. I think it may be partially contributed to camera shake at higher zoom levels. I am going to do some tests using a tri-pod and not using one. It seems to mostly happen at the higher end of the zoom, and not all the time.
