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 Nikon P520 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). Nikon P520 has external dimensions of 125 x 84 x 102 mm (4.92 x 3.31 x 4.02″) and weighs 550 g (1.21 lb / 19.40 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Nikon P520. Nikon P520 is 2mm narrower and 10mm shorter than Sony A7S but it is also 54mm thicker. As you can tell, actually this is not a fair size comparison since Nikon P520 has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, 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.
Sony A7S is 61g lighter than the Nikon P520 but we don't think this will make a significant difference.
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 A7S, the total kit will weigh much higher.
Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over P520 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon P520's 3.2" 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, Nikon P520 has a 18.0MP 1/2.3" (6.16 x 4.62 mm ) sized BSI-CMOS sensor .
Nikon P520's sensor provides 6MP 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 P520 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Nikon P520 Cameras
As seen above, Sony A7S has a 30.1x Larger sensor area than Nikon P520. 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.
