Its time to look a bit more closely at the Olympus E-M1 versus Panasonic GH2, one being a Pro Mirrorless and the latter is a Advanced Mirrorless by competitors Olympus and Panasonic. The image resolution of the E-M1 (16MP) and the GH2 (16MP) is relatively well matched and both cameras have the same sensor sizing (Four Thirds).

The E-M1 was announced 2 years later than the GH2 and that is quite a large gap as far as tech is concerned. Each of these cameras have the same body design (SLR-style mirrorless).

Before getting right into a in depth comparison, here is a short highlight of how the E-M1 grades versus the GH2 in regards to portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Olympus OM-D E-M1 and Panasonic Lumix DMC-GH2. The whole galleries are viewable at Olympus E-M1 Gallery and Panasonic GH2 Gallery.

When you are intending to lug around your camera, you'll need to think about its weight and size.

Generally, it can be tough to imagine the gap between sensor measurements simply by looking at specifications. The graphic below should provide you a much better sense of the sensor sizes in the E-M1 and GH2.

To sum up, the two cameras provide the same sensor dimensions and the exact same resolution so you should expect similar quality of photos but you should always take the production date of the products into consideration. The more recent E-M1 should have an edge when it comes to sensor technology.
