Olympus E-P3 vs Sony G3

Below, we will be comparing the Olympus E-P3 vs Sony G3, one being a Entry-Level Mirrorless and the latter is a Small Sensor Compact by competitors Olympus and Sony. The image resolution of the E-P3 (12MP) and the G3 (10MP) is relatively well matched but the E-P3 (Four Thirds) and G3 (1/2.3") feature different sensor measurements.

The E-P3 was manufactured 2 years later than the G3 and that is quite a significant gap as far as tech is concerned. Both cameras come with different body type with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Sony G3 being a Compact camera.

Before diving in to a detailed comparison, below is a short synopsis of how the E-P3 scores vs the G3 with regard to portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Olympus PEN E-P3 and Sony Cyber-shot DSC-G3. The entire galleries are provided at Olympus E-P3 Gallery and Sony G3 Gallery.

In case you're looking to lug around your camera frequently, you are going to need to consider its weight and proportions.

Often, it's hard to imagine the contrast between sensor measurements purely by checking a spec sheet. The photograph underneath should provide you a better sense of the sensor sizes in the E-P3 and G3.

Clearly, both of the cameras posses different megapixel count and different sensor measurements. The E-P3 featuring a bigger sensor is going to make achieving shallow DOF less difficult and the Olympus E-P3 will give more detail due to its extra 2 Megapixels. Higher resolution can also enable you to crop photographs somewhat more aggressively. The younger E-P3 provides an advantage in sensor technology.
