As you can tell, the 2 cameras posses the exact same sensor measurements albeit not the same MP. You should count on the Sony A58 to result in greater detail as a result of its extra 15MP. Higher resolution will help you crop photographs somewhat more aggressively. The older DP1 will be disadvantaged in sensor tech.
