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 Epson R-D1x 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). Epson R-D1x has external dimensions of 142 x 89 x 40 mm (5.59 x 3.5 x 1.57″) and weighs 620 g (1.37 lb / 21.87 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Epson R-D1x. Epson R-D1x is 5mm shorter and 8mm thinner than Sony A7S but it is also 15mm wider.

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 (131g ) than the Epson R-D1x 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 Epson R-D1x has a smaller APS-C sensor, Epson R-D1x'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 R-D1x which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S's 3 LCD screen is slightly larger than Epson R-D1x's 2.5" 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, Epson R-D1x 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, Epson R-D1x has a 6.0MP APS-C (23.7 x 15.6 mm ) sized CCD sensor .
Sony A7S's sensor provides 6MP more than Epson R-D1x'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 R-D1x sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Epson R-D1x Cameras
As seen above, Sony A7S has a 2.3x Larger sensor area than Epson R-D1x. 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 Epson R-D1x. There are 122 lenses for Sony A7S's Sony E mount, on the other hand there are only 59 lenses for Epson R-D1x's Leica M 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 0 lenses for Leica M mount with IS.
