Panasonic GX8 vs Pentax I-10 Sensor Comparison

Quite often, it is very difficult to visualize the gap between sensor sizing simply by going over specs. The graphic here should give you a clearer sense of the sensor dimensions in the GX8 and I-10.

As you can plainly see, the 2 cameras posses different megapixel count and different sensor sizing. The GX8 using its bigger sensor is going to make shooting shallow DOF less difficult and the Panasonic GX8 will deliver more detail using its extra 8MP. Higher resolution will allow you to crop shots somewhat more aggressively. The younger GX8 should have a benefit when it comes to sensor technology.
