Olympus E-PM1 vs Sony A300

Below, we are reviewing the Olympus E-PM1 versus Sony A300, one being a Entry-Level Mirrorless and the other is a Entry-Level DSLR by manufacturers Olympus and Sony. The image resolution of the E-PM1 (12MP) and the A300 (10MP) is fairly similar but the E-PM1 (Four Thirds) and A300 (APS-C) enjoy different sensor sizing.

The E-PM1 was manufactured 3 years later than the A300 and that is quite a large gap as far as tech is concerned. The two cameras come with different body type with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Sony A300 being a Compact SLR camera.

Before we go through a in-depth comparison, below is a brief synopsis of how the E-PM1 scores versus the A300 in the way of portability, imaging, features and an overall rating.

In many cases, its hard to imagine the difference between sensor sizing merely by reading specifications. The visual below will give you a better sense of the sensor measurements in the E-PM1 and A300.

Plainly, each of these cameras have got different megapixels and different sensor sizing. The E-PM1 because of its tinier sensor is going to make achieving shallower DOF more challenging and the Olympus E-PM1 will offer you greater detail due to its extra 2 Megapixels. Greater resolution will also allow you to crop images much more aggressively. The younger E-PM1 should have an advantage in sensor tech.
