Olympus E-M10 III vs Pentax S1 Sensor Comparison

Often, it is hard to visualize the difference in sensor sizing merely by viewing specifications. The visual underneath may provide you a much better sense of the sensor sizes in the E-M10 III and S1.

Plainly, both cameras feature different megapixels and different sensor sizing. The E-M10 III with its bigger sensor is going to make achieving shallower depth of field easier and the Olympus E-M10 III will render more detail using its extra 2 Megapixels. Higher resolution will also enable you to crop photographs way more aggressively. The fresher E-M10 III should have a benefit in sensor tech.
