As you can tell, both cameras feature different megapixel count and different sensor dimensions. The ZS25 due to its smaller sensor is going to make getting bokeh trickier and the Panasonic ZS25 will produce more detail due to its extra 10 Megapixels. Greater resolution will make it easier to crop images way more aggressively. The younger ZS25 provides an advantage with regard to sensor innovation.
