As you can plainly see, both the cameras have got different megapixel count and different sensor measurements. The EX-S5 having a smaller sensor is going to make getting shallow DOF harder and the Panasonic ZS100 will provide greater detail having an extra 11MP. Higher resolution can also enable you to crop pictures much more aggressively. The older EX-S5 will be disadvantaged when it comes to sensor innovation.
