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 Sony RX100 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). Sony RX100 has external dimensions of 102 x 58 x 36 mm (4 x 2.29 x 1.41″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Sony RX100. Sony RX100 is clearly the smaller of the two cameras. Its body is 25mm narrower, 36mm shorter and 12mm thinner than Sony A7S. As you can tell, actually this is not a fair size comparison since Sony RX100 has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony RX100 is significantly lighter (249g ) than the Sony A7S which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on A7S, the total kit will weigh much higher.
Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over RX100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Sony RX100'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 Sony RX100 has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
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, Sony RX100 has a 20.0MP 1" (13.2 x 8.8 mm ) sized CMOS sensor .
Sony RX100's sensor provides 8MP more than Sony A7S's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the A7S and RX100 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Sony RX100 Cameras
As seen above, Sony A7S has a 7.4x Larger sensor area than Sony RX100. 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 RX100 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, 21 points higher than RX100.
