Olympus E-M1 vs Panasonic G3

Below is a complete review of the Olympus E-M1 and Panasonic G3, former being a Pro Mirrorless while the latter is a Entry-Level Mirrorless by rivals Olympus and Panasonic. The resolution of the E-M1 (16MP) and the G3 (16MP) is relatively similar and both cameras posses the identical sensor sizes (Four Thirds).

The E-M1 was introduced 2 years later than the G3 and that is quite a sizable difference as far as technology is concerned. Each of these cameras feature the same body design (SLR-style mirrorless).

Before we go straight to a in-depth comparison, here is a brief highlight of how the E-M1 matches up vs the G3 for portability, imaging, features and an overall grade.

For those who are planning to lug around your camera frequently, you need to take into account its weight and measurements. The Olympus E-M1 comes with exterior dimensions of 130mm x 94mm x 63mm (5.1" x 3.7" x 2.5") along with a weight of 497 grams (1.10 lbs) while the Panasonic G3 has proportions of 115mm x 84mm x 47mm (4.5" x 3.3" x 1.9") with a weight of 336 grams (0.74 lbs).

Always remember, the weight of an ILC will differ depending on the lens you select at the time. Underneath is a front view measurements comparison of the E-M1 vs the G3.

Taking into consideration dimensions and weight, the portability score of the E-M1 and G3 is 71 and 83 respectively.

More often than not, its hard to picture the difference between sensor measurements merely by going over a spec sheet. The visual here might give you a much better sense of the sensor sizes in the E-M1 and G3.

Clearly, the 2 cameras feature the identical sensor size and the same MP therefore you can expect similar quality of photos but you really should take the age of the products into consideration. The newer E-M1 should have an advantage with regard to sensor technology.
