To sum up, the 2 cameras enjoy different megapixels and different sensor sizing. The EX-S7 due to its smaller sensor will make shooting shallower depth of field trickier and the Sigma Quattro will provide you with extra detail having its extra 17MP. Greater resolution can also allow you to crop images far more aggressively. The older EX-S7 will be disadvantaged in sensor tech.
