Panasonic ZS25 vs Samsung GX-20 Sensor Comparison

In many cases, it is difficult to imagine the difference between sensor sizes purely by looking at specifications. The pic here should provide you a better sense of the sensor sizes in the ZS25 and GX-20.

Plainly, the 2 cameras provide different megapixel count and different sensor sizes. The ZS25 using its tinier sensor is going to make getting shallow DOF trickier and the Panasonic ZS25 will give you extra detail because of its extra 1MP. Greater resolution will also make it easier to crop photos more aggressively. The fresher ZS25 should have a benefit in sensor technology.
