Often, it's tough to see the difference between sensor measurements purely by reviewing a spec sheet. The graphic below will give you a better sense of the sensor measurements in the EX-Z270 and NEX-3.

Clearly, each of these cameras have different resolutions and different sensor measurements. The EX-Z270 due to its tinier sensor will make shooting shallower DOF harder and the Sony NEX-3 will offer greater detail due to its extra 4MP. Higher resolution will let you crop pictures a bit more aggressively. The older EX-Z270 is going to be disadvantaged when it comes to sensor innovation.
