Olympus E-PL2 vs Sony A100

Below is a in depth comparison of the Olympus E-PL2 vs Sony A100, former being a Entry-Level Mirrorless while the latter is a Entry-Level DSLR by rivals Olympus and Sony. The sensor resolution of the E-PL2 (12MP) and the A100 (10MP) is relatively close but the E-PL2 (Four Thirds) and A100 (APS-C) have totally different sensor size.

The E-PL2 was announced 4 years later than the A100 and that is a fairly big difference as far as camera tech is concerned. Both of the cameras have different body design with the Olympus E-PL2 being a Rangefinder-style mirrorless camera and the Sony A100 being a Compact SLR camera.

Before delving straight to a full comparison, here is a brief overview of how the E-PL2 matches up versus the A100 in regards to portability, imaging, features and an overall grade.

In many cases, it is very hard to visualise the difference in sensor measurements merely by looking through a spec sheet. The visual below should give you a clearer sense of the sensor dimensions in the E-PL2 and A100.

Clearly, both of these cameras provide different megapixels and different sensor measurements. The E-PL2 having a smaller sensor will make getting shallower DOF more challenging and the Olympus E-PL2 will provide you with more detail with its extra 2MP. Higher resolution will make it easier to crop photographs more aggressively. The newer E-PL2 will have an edge when it comes to sensor innovation.
