Here, we are evaluating the Olympus E-5 versus Panasonic GH3, one is a Advanced DSLR and the other is a Advanced Mirrorless by manufacturers Olympus and Panasonic. There is a crucial difference among the sensor resolutions of the E-5 (12MP) and GH3 (16MP) but both cameras posses the identical sensor sizing (Four Thirds).

The E-5 was manufactured 19 months prior to the GH3 making them a generation away from each other. Both the cameras feature different body design with the Olympus E-5 being a Mid-size SLR camera and the Panasonic GH3 being a SLR-style mirrorless camera.

Before going right into a step-by-step comparison, here is a concise summation of how the E-5 matches up vs the GH3 with regard to portability, imaging, features and an overall mark.

Following is a sample of the gallery pics for Olympus E-5 and Panasonic Lumix DMC-GH3. The entire galleries are viewable at Olympus E-5 Gallery and Panasonic GH3 Gallery.

If you are looking to travel with your camera often, you're going to have to think about its weight and proportions. The Olympus E-5 enjoys outer measurements of 143mm x 117mm x 75mm (5.6" x 4.6" x 3.0") and a weight of 800 grams (1.76 lbs) while the Panasonic GH3 has measurements of 133mm x 93mm x 82mm (5.2" x 3.7" x 3.2") with a weight of 550 grams (1.21 lbs).

Remember, the weight of an Interchangeable Lens Camera will change depending on the lens you select at that moment. Underneath is a front view dimension comparison of the E-5 and the GH3.

Taking into consideration size and weight, the portability grade of the E-5 and GH3 is 58 and 66 respectively.

Generally, it is very hard to see the gap in sensor dimensions purely by going through a spec sheet. The picture here might offer you a better sense of the sensor measurements in the E-5 and GH3.

Clearly, the two cameras feature the identical sensor size but not the same megapixels. You should expect to see the Panasonic GH3 to show more detail due to its extra 4 Megapixels. Greater resolution will let you crop photos way more aggressively. The more aged E-5 will be disadvantaged in sensor technology.
