Sigma SD15 vs Sigma fp Sensor Comparison

Often, it is very hard to envision the difference in sensor sizing merely by seeing a spec sheet. The photograph underneath will offer you a much better sense of the sensor sizes in the SD15 and fp.

Clearly, both of the cameras enjoy different megapixels and different sensor sizing. The SD15 having a smaller sensor will make getting shallower DOF trickier and the Sigma fp will provide greater detail with its extra 20MP. Higher resolution will also allow you to crop shots far more aggressively. The older SD15 will be disadvantaged with regard to sensor technology.
