Sigma DP1x vs Sony TX30 Sensor Comparison

Generally, it's hard to see the contrast in sensor sizes just by checking out specifications. The pic below will help give you a much better sense of the sensor dimensions in the DP1x and TX30.

Plainly, each of the cameras feature different megapixel count and different sensor sizes. The DP1x using its bigger sensor will make getting shallow DOF simpler and the Sony TX30 will provide greater detail with its extra 13 Megapixels. Higher resolution can also let you crop pictures way more aggressively. The more aged DP1x will be disadvantaged when it comes to sensor innovation.
