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 TG-3 and Sony WX5 side-by-side from the front, back and top in their relative dimensions. Olympus TG-3 has external dimensions of 112 x 66 x 31 mm (4.41 x 2.6 x 1.22″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries). Sony WX5 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 146 g (0.32 lb / 5.15 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
