Olympus TG-1 iHS vs Sigma DP2 Merrill Sensor Comparison

More often than not, it can be hard to visualise the difference in sensor measurements merely by viewing a spec sheet. The visual underneath will help provide you a much better sense of the sensor dimensions in the TG-1 iHS and DP2 Merrill.

Clearly, both the cameras come with different megapixels and different sensor measurements. The TG-1 iHS due to its smaller sensor will make achieving shallower DOF trickier and the Sigma DP2 Merrill will result in greater detail having its extra 3MP. Higher resolution will also make it easier to crop pictures a good deal more aggressively.
