Panasonic G3 vs Samsung NX20 Sensor Comparison

Sometimes, it can be hard to imagine the contrast between sensor dimensions merely by checking a spec sheet. The picture here will offer you a greater sense of the sensor sizes in the G3 and NX20.

Clearly, each of the cameras enjoy different resolutions and different sensor dimensions. The G3 due to its tinier sensor is going to make shooting shallower DOF harder and the Samsung NX20 will give you greater detail utilizing its extra 4 Megapixels. Higher resolution will also make it easier to crop photographs far more aggressively. The more aged G3 is going to be disadvantaged in sensor tech.
