It is affecting overall color in large areas. That's why I brought it up. It's that bad.

Can you provide a screengrab where this CA is influencing the overall patina of the image? Like turn on/off CA correction and show the entire image's color change?

@ Stephen Ray #133:

The lens was a Zuiko 3.5/135. Concerning the CA: Did you turn on RT's amazing automatic CA correction (Raw tab)? The 2 screen shots show an area at utmost left at 400%, with and without CA correction.

Hening,

I have now tried RT auto CA correction. It helps but still not nearly satisfactory. Sorry, but a rather poor lens.

One might zoom into the attachment to better discern the color problems. (Grabbed from the center white flowers that should be more neutral without cyan artifacts as well as other colors.)

> a rather poor lens

I know. I'll buy a Zeiss ZF2 2.0/135 - if you carry it for me ;-)
