Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax Q7 is significantly lighter (289g ) 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 Pentax Q7 has a smaller 1/1.7" sensor, Pentax Q7'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 Q7 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Pentax Q7's LCD screens has the same diagonal size of 3.
On the other hand, Sony A7S features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Pentax Q7 has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
Both Sony A7S and Pentax Q7 have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Pentax Q7's sensor is 1/1.7" (7.44 x 5.58 mm ).
Since Sony A7S's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Pentax Q7.

Sensor Size and Resolution Comparison image of Sony A7S and Pentax Q7 Cameras
As seen above, Sony A7S has a 20.6x Larger sensor area than Pentax Q7. 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.
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 Pentax Q7. There are 122 lenses for Sony A7S's Sony E mount, on the other hand there are only 8 lenses for Pentax Q7's Pentax Q lens mount.
Another important factor is the availability of image stabilization. Pentax Q7 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 30 lenses for Sony E mount with Optical Image Stabilization features.
