Olympus E-510 vs Pentax Q7 Sensor Comparison

In many cases, it is very hard to visualise the gap between sensor sizing only by reviewing technical specs. The graphic here should give you a greater sense of the sensor sizing in the E-510 and Q7.

As you can tell, both of these cameras come with different megapixel count and different sensor sizing. The E-510 due to its larger sensor will make shooting shallower DOF less difficult and the Pentax Q7 will deliver more detail due to its extra 2MP. Greater resolution can also make it easier to crop pics a good deal more aggressively. The older E-510 is going to be behind with regard to sensor tech.
