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-620 UZ and Nikon L820 side-by-side from the front, back and top in their relative dimensions. Olympus SP-620 UZ has external dimensions of 110 x 74 x 74 mm (4.33 x 2.91 x 2.91″) and weighs 435 g (including batteries). Nikon L820 has external dimensions of 111 x 76 x 85 mm (4.37 x 2.99 x 3.35″) and weighs 470 g (1.04 lb / 16.58 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-620 UZ is 35g lighter than the Nikon L820 but we don't think this will make a significant difference.

Unfortunately neither the Olympus SP-620 UZ nor Nikon Coolpix L820 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus SP-620 UZ and Nikon L820's LCD screens have the same diagonal size of 3.00 inches.
