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 Fujifilm X100 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). Fujifilm X100 has external dimensions of 126 x 75 x 54 mm (4.96 x 2.95 x 2.13″) and weighs 445 g (0.98 lb / 15.70 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Fujifilm X100. Fujifilm X100 is 1mm narrower and 19mm shorter than Sony A7S but it is also 6mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm X100 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.
Fujifilm X100 is 44g lighter than the Sony A7S but we don't think this will make a significant difference.
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 X100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S's 3 LCD screen is slightly larger than Fujifilm X100's 2.8" screen.
In addition to the size advantage, Sony A7S LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Fujifilm X100 has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
Both Sony A7S and Fujifilm X100 have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Fujifilm X100's sensor is APS-C (23.6 x 15.8 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 Fujifilm X100.
One other difference between these two cameras that is worth mentioning is that Fujifilm X100's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.
Below you can see the A7S and X100 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Fujifilm X100 Cameras
As seen above, Sony A7S has a 2.3x Larger sensor area than Fujifilm X100. 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 Fujifilm X100 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, 14 points higher than X100.
