Ricoh CX1 vs Sigma DP1s Sensor Comparison

In many cases, it is very hard to see the contrast between sensor dimensions purely by reading through technical specs. The picture here might offer you a far better sense of the sensor measurements in the CX1 and DP1s.

As you can tell, the two cameras feature different megapixels and different sensor dimensions. The CX1 having a tinier sensor will make achieving shallow depth of field harder and the Ricoh CX1 will give greater detail having an extra 4MP. Higher resolution can also let you crop photographs way more aggressively. The more aged CX1 is going to be disadvantaged when it comes to sensor technology.
