Buying the DA 18-135? @135mm it could be better, but could also be worse.

CA is quite evident at 135mm in some images but getting down to 100mm and below its fine. Here is an image converted from a RAW file with minimal processing.

Zooming in on most of the frame shows CA at 135mm

This is cropped to the right hand edge.

The in-camera jpg processing does an excellent job correcting CA though. Below is the same image from the K-3 JPG with all corrections turned on.

I'll look forward to the review and feel free to add these images if the are of any use.

John.
