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 Samsung NX300M 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). Samsung NX300M has external dimensions of 122 x 64 x 41 mm (4.8 x 2.52 x 1.61″) and weighs 331 g (0.73 lb / 11.68 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Samsung NX300M. Samsung NX300M is clearly the smaller of the two cameras. Its body is 5mm narrower, 30mm shorter and 7mm thinner than Sony A7S.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung NX300M is significantly lighter (158g ) 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 Samsung NX300M has a smaller APS-C sensor, Samsung NX300M'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 NX300M which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Samsung NX300M's 3.3" LCD screen is slightly larger than Sony A7S's 3 screen.
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, Samsung NX300M has a 20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor.
Samsung NX300M's sensor provides 8MP more than Sony A7S'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 NX300M sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Samsung NX300M Cameras
As seen above, Sony A7S has a 2.3x Larger sensor area than Samsung NX300M. 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 Samsung NX300M. There are 128 lenses for Sony A7S's Sony E mount, on the other hand there are only 32 lenses for Samsung NX300M's Samsung NX 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 31 lenses for Sony E mount and 7 lenses for Samsung NX mount with IS.
