Olympus SH-2 vs Pentax K20D Sensor Comparison

Oftentimes, it can be tough to see the contrast in sensor sizing purely by going through specs. The photograph here may give you a far better sense of the sensor measurements in the SH-2 and K20D.

All in all, both of the cameras posses different megapixels and different sensor sizing. The SH-2 using its smaller sensor will make shooting shallower DOF trickier and the Olympus SH-2 will produce greater detail because of its extra 1 Megapixels. Higher resolution will let you crop shots somewhat more aggressively. The younger SH-2 is going to have an edge with regard to sensor technology.
