Its time to look more in depth at the Panasonic GM5 and Sony A3000, both Entry-Level Mirrorless cameras by brands Panasonic and Sony. The sensor resolution of the GM5 (16MP) and the A3000 (20MP) is very close but the GM5 (Four Thirds) and A3000 (APS-C) have different sensor size.

Often, it is very difficult to picture the gap in sensor sizes purely by viewing specs. The picture below may give you a much better sense of the sensor sizes in the GM5 and A3000.

All in all, the 2 cameras provide different resolutions and different sensor sizes. The GM5 having a smaller sensor is going to make getting shallow DOF more challenging and the Sony A3000 will render extra detail using its extra 4MP. Greater resolution will also allow you to crop pics more aggressively. The newer GM5 should have a benefit when it comes to sensor innovation.
