So shot raw an post process the CA out. Are there files that do it for you? What program do I need to download (free is best . . .)

The images I was talking about was shot in jpeg and it seems like there is not much you can do once that file is written.

Thanks for the info!

As you mentioned, Canon's DPP software is free. I use the Digital Lens Optimizer function to clean up CA. You have to download a profile for each lens you want to correct.
