Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Sony A7S and Panasonic GH2 side-by-side from the front, back and top in their relative dimensions. Sony A7S has external dimensions of 127 x 94 x 48 mm (5 x 3.7 x 1.89″) and weighs 489 g (1.08 lb / 17.25 oz) (including batteries). Panasonic GH2 has external dimensions of 124 x 90 x 76 mm (4.88 x 3.54 x 2.99″) and weighs 442 g (0.97 lb / 15.59 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Panasonic GH2. Panasonic GH2 is 3mm narrower and 4mm shorter than Sony A7S but it is also 28mm thicker.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic GH2 is 47g lighter than the Sony A7S but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Sony A7S has a Full frame sensor and Panasonic GH2 has a smaller Four Thirds sensor, Panasonic GH2's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7S lenses.

Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over GH2 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Panasonic GH2's LCD screens has the same diagonal size of 3.
Sony A7S features a
Tilting only screen which is mostly only good for shooting from waist or over the head levels. On the other hand, Panasonic GH2 sports a
Fully Articulated screen which is more flexible and useful especially for taking Selfie shots and video.
Sony A7S has a 12.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Panasonic GH2 has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor.
Below you can see the A7S and GH2 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Panasonic GH2 Cameras
As seen above, Sony A7S has a 3.8x Larger sensor area than Panasonic GH2. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
Both Sony A7S and Panasonic GH2 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, A7S has scored 87, 27 points higher than GH2.

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Sony A7S has an advantage over Panasonic GH2. There are 122 lenses for Sony A7S's Sony E mount, on the other hand there are only 107 lenses for Panasonic GH2's Micro Four Thirds lens mount.
Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 30 lenses for Sony E mount and 31 lenses for Micro Four Thirds mount with IS.
