How much is the Lumix 100-300 CA contributing to deterioration of the image on the E-M5 and what's the best approach to fixing it in the PS/LR or other RAW converters?

I tried both the Pan 100-300 and Oly 75-300 II and liked Pan more, especially at the long end. What I see in the files from Pan is probably a combination of its modest res + CA, but nothing horrible. I'm looking for more effective improvement of the file quality than what I currently get. Photozone, I don't pay much attention to z a single lens test results.
Thanks for your input.
