Olympus E-PM1 vs Pentax WG-1

The following is a in-depth assessment of the Olympus E-PM1 vs Pentax WG-1, one is a Entry-Level Mirrorless and the other is a Waterproof by companies Olympus and Pentax. The resolution of the E-PM1 (12MP) and the WG-1 (14MP) is very close but the E-PM1 (Four Thirds) and WG-1 (1/2.3") posses totally different sensor dimensions.

Oftentimes, it is hard to envision the difference in sensor dimensions simply by viewing specifications. The pic here will provide you a far better sense of the sensor sizes in the E-PM1 and WG-1.

Plainly, both the cameras have different resolutions and different sensor dimensions. The E-PM1 having a larger sensor will make getting shallower DOF simpler and the Pentax WG-1 will provide you with extra detail with its extra 2 Megapixels. Greater resolution can also help you crop pics a bit more aggressively. The more modern E-PM1 is going to have an edge in sensor innovation.
