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 Olympus SP-820UZ and Nikon P500 side-by-side from the front, back and top in their relative dimensions. Olympus SP-820UZ has external dimensions of and weighs 485 g (1.07 lb / 17.11 oz) (including batteries). Nikon P500 has external dimensions of 116 x 84 x 10 mm (4.57 x 3.31 x 4.06″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries).

Now lets look at the top view comparison of Olympus SP-820UZ and Nikon P500.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-820UZ is 9g lighter than the Nikon P500 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus Stylus SP-820UZ nor Nikon Coolpix P500 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
Olympus SP-820UZ and Nikon P500's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P500 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Olympus SP-820UZ has a fixed type screen which provides less flexibility in shooting positions compared to P500.
