To sum up, the two cameras come with different resolutions and different sensor sizes. The EX-Z29 with its smaller sensor is going to make getting shallow depth of field more difficult and the Sony A57 will render greater detail using its extra 6 Megapixels. Greater resolution can also let you crop photos a good deal more aggressively. The more aged EX-Z29 will be disadvantaged in sensor tech.
