Canon 20D vs Sigma SD9 Sensor Comparison

Oftentimes, its tough to visualise the gap in sensor measurements just by viewing a spec sheet. The visual underneath should offer you a more clear sense of the sensor dimensions in the 20D and SD9.

As you can see, each of these cameras posses the exact same sensor measurements albeit not the same MP. You can count on the Canon 20D to render more detail having an extra 5MP. Higher resolution can also make it easier to crop shots somewhat more aggressively. The younger 20D will have an edge when it comes to sensor tech.
