Sigma DP2 Merrill vs Sony A7c Sensor Comparison

In many cases, it is difficult to visualize the gap between sensor dimensions purely by reviewing technical specs. The pic underneath may provide you a stronger sense of the sensor dimensions in the DP2 Merrill and A7c.

As you can tell, both of these cameras come with different megapixel count and different sensor dimensions. The DP2 Merrill due to its tinier sensor is going to make shooting shallow DOF harder and the Sony A7c will offer you extra detail as a result of its extra 9 Megapixels. Greater resolution can also make it easier to crop images a good deal more aggressively. The more aged DP2 Merrill is going to be behind when it comes to sensor innovation.
