Canon SX420 IS vs Sigma DP2s Sensor Comparison

Oftentimes, it can be hard to see the contrast in sensor dimensions just by going through a spec sheet. The image underneath might give you a clearer sense of the sensor measurements in the SX420 IS and DP2s.

Clearly, the two cameras enjoy different resolutions and different sensor dimensions. The SX420 IS due to its smaller sensor will make shooting shallower DOF harder and the Canon SX420 IS will produce greater detail due to its extra 15MP. Greater resolution will allow you to crop images far more aggressively. The more recent SX420 IS will have an advantage in sensor technology.
