Where are you seeing it on here? Is it in combination of some lens or camera or processing?

  • Most lenses have it, unless apochromatic design
  • Can degrade sharpness overall
  • Can be distracting for some subjects
  • Digital images are easily corrected with the appropriate software
  • Probably the most common "fault" associated with any particular lens. The severity of the fault is logarithmically proportional to the price of the lens.

Well, my post was asked because I wanted to see the context the CA was mentioned, then I would have answered.

I'm glad others were able to answer and now I know too.
