I think CA correction has been discussed before, may be I should have used
purple fringe instead, I haven't seen any software that can correct them.
Here are two more samples (last time I posted the Tamron 180/2.5 sample):
- Tamron 70-300 Di LD Macro which Larry just posted some nice flower images,
the lens is sharp from 70-200 if not for the purple fringe it would be great

- The problem is not limited to low cost zoom, the DZ8mm also suffered from
this problem:
