Clearly, the 2 cameras have got different resolutions and different sensor measurements. The EX-Z550 using its tinier sensor will make shooting shallower depth of field harder and the Casio EX-Z550 will give you more detail with its extra 2MP. Greater resolution will make it easier to crop pics much more aggressively. The older EX-Z550 is going to be disadvantaged in sensor innovation.
