Sony Cyber-shot DSC-W220 Digital Camera Review at CNET Reviews – Joshua Goldman:
Center sharpness and detail on the W220 is very good. However, it drops off to the sides, making the edges and corners of photos look very soft. A certain amount of purple fringing is to be expected, but the W220 was above average to the point where it's clearly visible in prints above 4×6 inches. Lastly, colors, while not quite accurate, are nice and look natural.
Joshua gave the Sony W220 an overall rating score of 3.5 out of 5 stars (VERY GOOD).
