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 Pentax X-5 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). Pentax X-5 has external dimensions of 119 x 86 x 107 mm (4.69 x 3.39 x 4.21″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Pentax X-5. Pentax X-5 is 8mm narrower and 8mm shorter than Sony A7S but it is also 59mm thicker. As you can tell, actually this is not a fair size comparison since Pentax X-5 has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, its thickness will increase significantly.

Now lets look at the top view comparison of Sony A7S and Pentax X-5.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A7S is significantly lighter (106g ) than the Pentax X-5 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 X-5 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Pentax X-5'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.
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, Pentax X-5 has a 16.0MP 1/2.3" (6.08 x 4.56 mm ) sized BSI-CMOS sensor .
Below you can see the A7S and X-5 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A7S and Pentax X-5 Cameras
