Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus E-P5 is significantly lighter (69g ) than the Sony A7S 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 Olympus E-P5 has a smaller Four Thirds sensor, Olympus E-P5's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7S lenses.

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 Olympus E-P5. There are 128 lenses for Sony A7S's Sony E mount, on the other hand there are only 107 lenses for Olympus E-P5's Micro Four Thirds lens mount.
Another important factor is the availability of image stabilization. Olympus E-P5 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.
