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 SZ-30MR and Nikon L810 side-by-side from the front, back and top in their relative dimensions. Olympus SZ-30MR has external dimensions of 106 x 69 x 40 mm (4.17 x 2.72 x 1.57″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-30MR is significantly lighter (204g ) than the Nikon L810 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus SZ-30MR nor Nikon Coolpix L810 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus SZ-30MR and Nikon L810's LCD screens have the same diagonal size of 3.00 inches.
