Often, its difficult to imagine the gap in sensor dimensions only by going through a spec sheet. The picture underneath will give you a better sense of the sensor measurements in the TG-1 iHS and DP3 Merrill.

As you can see, the two cameras come with different resolutions and different sensor dimensions. The TG-1 iHS using its smaller sensor is going to make shooting shallow depth of field tougher and the Sigma DP3 Merrill will provide more detail using its extra 3 Megapixels. Greater resolution will enable you to crop pics a good deal more aggressively. The more aged TG-1 iHS will be disadvantaged when it comes to sensor innovation.
