Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A7S is significantly lighter (129g ) than the Sony A57 which may become a big advantage especially on long walking trips.
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 Sony A57 has a smaller APS-C sensor, Sony A57's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7S lenses.

Sensor Size and Resolution Comparison image of Sony A7S and Sony A57 Cameras
As seen above, Sony A7S has a 2.3x Larger sensor area than Sony A57. 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 Sony A57 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, 12 points higher than A57.

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 A57 has an advantage over Sony A7S There are 143 lenses for Sony A57's Sony/Minolta Alpha mount, on the other hand there are only 128 lenses for Sony A7S's Sony E lens mount.
Another important factor is the availability of image stabilization. Sony A57 has a big advantage in this regard because it has a sensor based image stabilization which means that all the lenses mounted to this body will be stabilized. On the other hand, Sony A7S doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 31 lenses for Sony E mount with Optical Image Stabilization features.
