Canon G7 X vs Sigma DP2 Sensor Comparison

Typically, its difficult to visualise the contrast in sensor sizes simply by looking through technical specs. The image underneath might offer you a much better sense of the sensor dimensions in the G7 X and DP2.

As you can tell, the 2 cameras have different megapixel count and different sensor sizes. The G7 X having a smaller sensor will make achieving shallower depth of field trickier and the Canon G7 X will render extra detail with its extra 15MP. Higher resolution will allow you to crop photographs a bit more aggressively. The younger G7 X is going to have an advantage in sensor innovation.
