Sony A7R III vs Samsung NX3000: Physical Specs and Body Features Comparison

Size and weight are big decision factors when you are trying to find the ideal camera for your needs. In this section, we are going to illustrate the Sony A7R III and Samsung NX3000 side-by-side from the front, back and top in their relative dimensions. Sony A7R III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 657 g (1.45 lb / 23.17 oz) (including batteries). Samsung NX3000 has external dimensions of 117 x 66 x 39 mm (4.61 x 2.6 x 1.54″) and weighs 230 g (including batteries).

Below you can see the front-view size comparison of the Sony A7R III and the Samsung NX3000. Samsung NX3000 is clearly the smaller of the two cameras. Its body is 10mm narrower, 30mm shorter and 35mm thinner than Sony A7R III.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day. Samsung NX3000 is significantly lighter (427g ) 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 also have to take into account the lenses that you will be using with these bodies. Since Sony A7R III has a Full frame sensor and Samsung NX3000 has a smaller APS-C sensor, Samsung NX3000'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 the A7R III has a big advantage over the NX3000 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7R III and Samsung NX3000's LCD screens have the same diagonal size of 3.00 inches.

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 A7R III vs Samsung NX3000: Sensor Comparison

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 NX3000 has a 20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .

Sony A7R III's sensor provides 22MP more than Samsung NX3000'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 moiré occurring in certain scenes.

Below you can see the A7R III and NX3000 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7R III and Samsung NX3000 Cameras


As seen above, Sony A7R III has a 2.3x Larger sensor area than Samsung NX3000. 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.

Sony A7R III vs Samsung NX3000 Comparison of Available Lenses
Which camera has more lenses?

The number of available lenses is a big deciding factor when choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that the Sony A7R III has an advantage over the Samsung NX3000. There are 201 lenses for the Sony A7R III's Sony E mount, but on the other hand, there are only 34 lenses for the Samsung NX3000'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 for compensating vibration up to 5.0-stops according to CIPA standards.
On the other hand, Samsung NX3000 doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 7 lenses for Samsung NX mount with Optical Image Stabilization features.
