Olympus E-3 vs Sony G3

Below is a in-depth comparison of the Olympus E-3 and Sony G3, one being a Advanced DSLR and the other is a Small Sensor Compact by rivals Olympus and Sony. The sensor resolution of the E-3 (10MP) and the G3 (10MP) is fairly similar but the E-3 (Four Thirds) and G3 (1/2.3") have totally different sensor sizes.

The E-3 was introduced 10 months prior to the G3 and they are both of a similar generation. Both the cameras feature different body design with the Olympus E-3 being a Mid-size SLR camera and the Sony G3 being a Compact camera.

Before diving right into a in-depth comparison, here is a brief summation of how the E-3 grades against the G3 with respect to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Olympus E-3 and Sony Cyber-shot DSC-G3. The whole galleries are provided at Olympus E-3 Gallery and Sony G3 Gallery.

If you're looking to lug around your camera regularly, you'll need to consider its weight and dimensions. The Olympus E-3 features exterior dimensions of 142mm x 116mm x 75mm (5.6" x 4.6" x 3.0") accompanied by a weight of 890 grams (1.96 lbs) while the Sony G3 has dimensions of 97mm x 59mm x 22mm (3.8" x 2.3" x 0.9") and a weight of 185 grams (0.41 lbs).

More often than not, it is very difficult to envision the difference between sensor measurements only by reading a spec sheet. The graphic underneath will give you a clearer sense of the sensor dimensions in the E-3 and G3.

As you can see, both cameras come with the identical megapixel count but not the same sensor measurements. The E-3 uses the larger sensor which should make achieving shallow depth of field less difficult. The older E-3 is going to be behind with regard to sensor tech.
