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 Olympus XZ-2 iHS 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). Olympus XZ-2 iHS has external dimensions of 113 x 65 x 48 mm (4.45 x 2.56 x 1.89″) and weighs 346 g (0.76 lb / 12.20 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Olympus XZ-2 iHS. Olympus XZ-2 iHS is 14mm narrower and 29mm shorter than Sony A7S but they have the same thickness of 48mm. As you can tell, actually this is not a fair size comparison since Olympus XZ-2 iHS 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.
Olympus XZ-2 iHS is significantly lighter (143g ) 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 XZ-2 iHS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Olympus XZ-2 iHS's LCD screens has the same diagonal size of 3.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over the head levels.
Both Sony A7S and Olympus XZ-2 iHS have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Olympus XZ-2 iHS'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 Olympus XZ-2 iHS.
Below you can see the A7S and XZ-2 iHS sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Olympus XZ-2 iHS Cameras
As seen above, Sony A7S has a 20.6x Larger sensor area than Olympus XZ-2 iHS. 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 Olympus XZ-2 iHS 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, 38 points higher than XZ-2 iHS.
