Often, it can be tough to visualise the difference in sensor sizing purely by going through technical specs. The graphic here may give you a much better sense of the sensor measurements in the G5 and K-7.

As you have seen, the two cameras have different megapixels and different sensor sizing. The G5 featuring a smaller sensor will make achieving shallower DOF tougher and the Panasonic G5 will produce more detail due to its extra 1MP. Higher resolution can also enable you to crop shots a bit more aggressively. The more recent G5 will have an edge with regard to sensor innovation.
