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 Nikon P520 and Nikon L830 side-by-side from the front, back and top in their relative dimensions. 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). Nikon L830 has external dimensions of 110 x 76 x 91 mm (4.33 x 2.99 x 3.58″) and weighs 508 g (1.12 lb / 17.92 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P520 and the Nikon L830. Nikon L830 is clearly the smaller of the two cameras. Its body is 15mm narrower, 8mm shorter and 11mm thinner than Nikon P520.
Here is the back view size comparison of the Nikon P520 and Nikon L830.
Now lets look at the top view comparison of Nikon P520 and Nikon L830.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L830 is 42g lighter than the Nikon P520 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix P520 nor Nikon Coolpix L830 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
