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 Nikon L840 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). Nikon L840 has external dimensions of 114 x 89 x 96 mm (4.49 x 3.5 x 3.78″) and weighs 538 g (1.19 lb / 18.98 oz) (including batteries).
Below you can see the front view size comparison of Sony A7R III and Nikon L840. Nikon L840 is 13mm narrower and 7mm shorter than Sony A7R III but it is also 22mm thicker. As you can tell, actually this is not a fair size comparison since Nikon L840 has a built-in lens but Sony A7R III doesn't. Once you put a lens on A7R III, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L840 is significantly lighter (119g ) than the Sony A7R III which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on A7R III, the total kit will weigh much higher.
Weather Sealing
With its weather sealed body, we believe that A7R III has a big advantage over L840 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7R III and Nikon L840'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 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, Nikon L840 has a 16.0MP 1/2.3" (6.17 x 4.55 mm ) sized CMOS sensor .
Sony A7R III's sensor provides 26MP more than Nikon L840'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.
