There is a crucial difference between the image resolutions of the G2 (12MP) and GH3 (16MP) but they use the exact same sensor sizes (Four Thirds).

The G2 was launched 3 years before the GH3 and that is quite a serious gap as far as tech is concerned. Both of the cameras come with the identical body type (SLR-style mirrorless).

Before delving in to a more detailed comparison, below is a short introduction of how the G2 grades against the GH3 when it comes to portability, imaging, features and an overall rating.

Here is a preview of the gallery images for Panasonic Lumix DMC-G2 and Panasonic Lumix DMC-GH3. The complete galleries are provided at Panasonic G2 Gallery and Panasonic GH3 Gallery.

Often, its hard to see the difference between sensor sizing only by checking a spec sheet. The visual here should provide you a better sense of the sensor sizes in the G2 and GH3.

As you can see, the two cameras have got the exact same sensor measurements albeit not the same MP. You should expect the Panasonic GH3 to give extra detail utilizing its extra 4 Megapixels. Higher resolution will let you crop pictures much more aggressively. The older G2 is going to be disadvantaged when it comes to sensor tech.
