So far I've been shooting with my DSLR and I know little about prosumer digicam as far as quality is concerned. But I have observed that chromatic aberration (c.a.) is often, if not always, a problem. There have been complaints even with newer models like the Canon G5 and the latest A80.

Is there a digicam that shows the least c.a.? Also, with the new A80 that comes with swivel LCD, I'm getting confused over the choices. What are the pros and cons of the A80, S50 or a G5 by comparing among themselves in terms of image quality and ease of use?
