Olympus E-P3 vs Panasonic ZS25 Sensor Comparison

Sometimes, it is very tough to visualize the difference between sensor sizes simply by checking specifications. The image underneath will help give you a greater sense of the sensor measurements in the E-P3 and ZS25.

Plainly, the 2 cameras feature different megapixel count and different sensor sizes. The E-P3 with its larger sensor is going to make shooting shallower DOF easier and the Panasonic ZS25 will give greater detail because of its extra 4 Megapixels. Greater resolution can also let you crop pics way more aggressively. The more aged E-P3 is going to be behind when it comes to sensor innovation.
