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 A7R III and Samsung Galaxy NX side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung Galaxy NX is significantly lighter (162g ) than the Sony A7R III 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 A7R III has a Full frame sensor and Samsung Galaxy NX has a smaller APS-C sensor, Samsung Galaxy NX's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7R III lenses.

Weather Sealing
With its weather sealed body, we believe that A7R III has a big advantage over Galaxy NX which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Samsung Galaxy NX's 4.8" LCD screen is slightly larger than Sony A7R III's 3 screen.
On the other hand, Sony A7R III LCD screen 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, Samsung Galaxy NX has a fixed type screen which provides less flexibility in shooting positions compared to A7R III.
Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Samsung Galaxy NX has a 20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor.
Sony A7R III's sensor provides 22MP more than Samsung Galaxy NX'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.
Another difference between these two cameras is that Sony A7R III's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Sensor Size and Resolution Comparison image of Sony A7R III and Samsung Galaxy NX Cameras
As seen above, Sony A7R III has a 2.3x Larger sensor area than Samsung Galaxy NX. 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 A7R III has an advantage over Samsung Galaxy NX. There are 128 lenses for Sony A7R III's Sony E mount, on the other hand there are only 32 lenses for Samsung Galaxy NX's Samsung NX lens mount.
Another important factor is the availability of image stabilization. Sony A7R III has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. A7R III's built-in Image stabilization system is effective to compensate vibration up to 5.0-stops according to CIPA standards.7 lenses for Samsung NX mount with Optical Image Stabilization features.
