Panasonic ZS100 vs Pentax RZ18 Sensor Comparison

Sometimes, it is very difficult to visualise the gap in sensor dimensions purely by checking out specs. The picture here might give you a more clear sense of the sensor sizes in the ZS100 and RZ18.

As you can plainly see, both cameras have different megapixels and different sensor dimensions. The ZS100 using its bigger sensor will make shooting shallower DOF less difficult and the Panasonic ZS100 will show greater detail because of its extra 4 Megapixels. Higher resolution can also let you crop photographs a bit more aggressively. The younger ZS100 is going to have an edge when it comes to sensor tech.
