Considering dimensions and weight, the portability grade of the E-P5 and S1 is 85 and 54 respectively.

Normally, it can be hard to picture the gap in sensor sizing only by seeing a spec sheet. The graphic below might provide you a more clear sense of the sensor dimensions in the E-P5 and S1.

As you can see, both of these cameras have got different megapixels and different sensor sizing. The E-P5 featuring a smaller sensor is going to make getting shallow depth of field trickier and the Panasonic S1 will provide extra detail due to its extra 8MP. Greater resolution will make it easier to crop pics much more aggressively. The older E-P5 will be behind in sensor innovation.
