Casio EX-Z270 vs Sony TX55 Sensor Comparison

Usually, it's tough to visualise the contrast between sensor dimensions only by looking at technical specs. The image underneath will give you a stronger sense of the sensor sizing in the EX-Z270 and TX55.

As you have seen, both of these cameras have different resolutions and different sensor dimensions. The EX-Z270 with its tinier sensor will make getting shallower depth of field harder and the Sony TX55 will resolve greater detail because of its extra 6 Megapixels. Greater resolution will let you crop photos a bit more aggressively. The more aged EX-Z270 is going to be disadvantaged with regard to sensor tech.
