I've looked at her example of CA, and struggled to see it without zooming in to such an extreme that the picture quality had already degraded into a mess of 'jaggies'. I'd like to think I can be objective over the good and bad of 'my' brand of camera, but I really can't see the extreme CA she complained of.

Won't the retailer take it back, maybe with a restocking charge?

You don't say where the photos 'came out' - rear lcd? In pp software?

Could be a card problem.
