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 X-A1 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 X-A1 has external dimensions of 117 x 67 x 39 mm (4.6 x 2.62 x 1.54″) and weighs 330 g (0.73 lb / 11.64 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Fujifilm X-A1. Fujifilm X-A1 is clearly the smaller of the two cameras. Its body is 10mm narrower, 27mm shorter and 9mm thinner than Sony A7S.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A1 is significantly lighter (159g ) 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 Fujifilm X-A1 has a smaller APS-C sensor, Fujifilm X-A1'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 X-A1 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Fujifilm X-A1'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, Fujifilm X-A1 has a 16.0MP APS-C (23.6 x 15.6 mm ) sized CMOS sensor and features EXR Processor II processor.
Below you can see the A7S and X-A1 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Fujifilm X-A1 Cameras
As seen above, Sony A7S has a 2.3x Larger sensor area than Fujifilm X-A1. 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 Fujifilm X-A1. There are 122 lenses for Sony A7S's Sony E mount, on the other hand there are only 54 lenses for Fujifilm X-A1's Fujifilm X lens mount.
Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 30 lenses for Sony E mount and 12 lenses for Fujifilm X mount with IS.
