Pentax X-5 vs Sigma SD15 Sensor Comparison

Normally, it can be hard to visualize the gap in sensor sizing simply by researching a spec sheet. The graphic below will provide you a far better sense of the sensor dimensions in the X-5 and SD15.

Clearly, each of these cameras have different megapixels and different sensor sizing. The X-5 having a smaller sensor is going to make achieving shallower DOF more difficult and the Pentax X-5 will result in extra detail because of its extra 11 Megapixels. Higher resolution can also let you crop pictures a bit more aggressively. The more modern X-5 provides an advantage when it comes to sensor technology.
