Pentax X70 vs Sigma DP1x Sensor Comparison

Generally, its hard to visualize the gap in sensor measurements merely by going through technical specs. The graphic below will help provide you a more clear sense of the sensor sizing in the X70 and DP1x.

As you have seen, both of these cameras feature different megapixels and different sensor measurements. The X70 featuring a smaller sensor is going to make shooting shallow depth of field trickier and the Pentax X70 will produce greater detail due to its extra 7 Megapixels. Higher resolution will help you crop pictures way more aggressively. The older X70 will be disadvantaged with regard to sensor tech.
