Haven't posted for a while due to helping my big sister out with a presentation on innovations in theatrical scene painting over the last 450 years. Took loads of pictures then had to edit them down and teach her to use Powerpoint, good fun but time consuming ! Anyway, thought I'd post this taken last year but only printed just recently. Hopefully the colour won't come out to garish on your screens:
It was taken when I was trying out a Sigma 12-24mm. Stopped right down for maximum depth of field and it shows a big problem with chromatic aberration at the edges - big blue lines above the leaves at the bottom of the picture. Here's a 100% view:
Centre of the image is fine.
Couldn't fix the problem with the CS2 lens correction filter so might have to be do something laborious next time.

Another time you might find that PS's RAW conversion offers more adjustment for CA, failing that you can always run the lens correction filter more than once ;o)
Going for an aperture in the mid range may perform better than totally stopped down.
A manual workaround the blue fringing would be to use the color range selection tool to select all the blue fringing, then hide selection so you can see what you are doing then selectively burn/doge/desaturate/recolour the fringing. Used this technique a couple of times and it can work quite well.
