Sigma DP2x vs Sony A7c Sensor Comparison

In many cases, it is tough to imagine the difference between sensor measurements just by reading specs. The visual here may give you a better sense of the sensor dimensions in the DP2x and A7c.

As you can plainly see, both of the cameras enjoy different megapixels and different sensor measurements. The DP2x featuring a tinier sensor is going to make achieving shallower depth of field harder and the Sony A7c will deliver extra detail due to its extra 19 Megapixels. Greater resolution can also help you crop images far more aggressively. The older DP2x is going to be disadvantaged when it comes to sensor innovation.
