Olympus E-P2 vs Panasonic G3

Let's look a little more closely at the Olympus E-P2 versus Panasonic G3, both Entry-Level Mirrorless digital cameras by competitors Olympus and Panasonic. There exists a big gap between the sensor resolutions of the E-P2 (12MP) and G3 (16MP) but both cameras provide the same sensor dimensions (Four Thirds).

The E-P2 was revealed 14 months earlier than the G3 making them a generation away from one another. Both the cameras have different body design with the Olympus E-P2 being a Rangefinder-style mirrorless camera and the Panasonic G3 being a SLR-style mirrorless camera.

Before going into a comprehensive comparison, here is a short synopsis of how the E-P2 matches up vs the G3 when it comes to portability, imaging, features and an overall mark.

Below is a sample of the gallery pictures for Olympus PEN E-P2 and Panasonic Lumix DMC-G3. The full galleries are available at Olympus E-P2 Gallery and Panasonic G3 Gallery.

For anyone who is going to travel with your camera regularly, you will need to consider its weight and volume. The Olympus E-P2 provides outer measurements of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") and a weight of 355 grams (0.78 lbs) while the Panasonic G3 has sizing of 115mm x 84mm x 47mm (4.5" x 3.3" x 1.9") and a weight of 336 grams (0.74 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilising at the time. The following is a front view dimension comparison of the E-P2 against the G3.

Considering dimensions and weight, the portability score of the E-P2 and G3 is 86 and 83 respectively.

More often than not, it's hard to visualise the gap between sensor dimensions only by looking at specs. The image here might provide you a better sense of the sensor sizing in the E-P2 and G3.

As you can plainly see, each of the cameras have the same sensor dimensions but not the same resolution. You should anticipate the Panasonic G3 to give you more detail because of its extra 4 Megapixels. Greater resolution will make it easier to crop images a bit more aggressively. The more aged E-P2 is going to be behind in sensor technology.
