Olympus SZ-31MR iHS vs Sony A7c Sensor Comparison

Oftentimes, it is very difficult to picture the difference in sensor measurements purely by seeing a spec sheet. The visual here may provide you a much better sense of the sensor sizing in the SZ-31MR iHS and A7c.

Clearly, the 2 cameras posses different resolutions and different sensor measurements. The SZ-31MR iHS due to its smaller sensor is going to make achieving shallow depth of field harder and the Sony A7c will produce extra detail due to its extra 8 Megapixels. Higher resolution can also make it easier to crop pictures somewhat more aggressively. The older SZ-31MR iHS will be disadvantaged with regard to sensor technology.
