Casio EX-Z800 vs Olympus TG-870 Sensor Comparison

Oftentimes, it is difficult to visualise the difference in sensor measurements merely by viewing a spec sheet. The photograph here might offer you a better sense of the sensor dimensions in the EX-Z800 and TG-870.

Clearly, the 2 cameras provide the same sensor dimensions albeit not the same megapixels. You should expect the Olympus TG-870 to render extra detail due to its extra 2 Megapixels. Higher resolution will make it easier to crop photographs more aggressively. The older EX-Z800 will be disadvantaged in sensor tech.
