Sony Cyber-shot DSC-TX20 Digital Camera Review$329.99
Chromatic aberration is terribly severe, and this is very obvious from the crops below. Note the bright blue and orange fringing that occurs in high contrast areas. This problem is normally associated with a low quality lens, and given the severity here, we'd guess Sony is using a plastic lens instead of a glass one.
Fringing also affects many of our sample photos, which may be found here.
If you're concerned about barrel distortion, just zoom in. It's as simple as that. For some reason the TX20 produces extremely severe distortion at the closest focal length, but the problem completely disappears halfway down the focal range. Perhaps some software is compensating here, that's fairly common, but for whatever reason distortion is simply gone after 2x. We can hardly complain.
