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 HX100V and Nikon P520 side-by-side from the front, back and top in their relative dimensions. Sony HX100V has external dimensions of 122 x 87 x 93 mm (4.8 x 3.43 x 3.66″) and weighs 577 g (1.27 lb / 20.35 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 the Sony HX100V and the Nikon P520. Sony HX100V is 3mm narrower and 9mm thinner than Nikon P520 but it is also 3mm taller.
Here is the back view size comparison of the Sony HX100V and Nikon P520.
Now lets look at the top view comparison of Sony HX100V and Nikon P520.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P520 is 27g lighter than the Sony HX100V but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX100V nor Nikon Coolpix P520 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon P520's 3.20" LCD screen is slightly larger than Sony HX100V's 3 screen.
