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 Pentax WG-3 and Olympus TG-860 side-by-side from the front, back and top in their relative dimensions. Pentax WG-3 has external dimensions of 124 x 64 x 33 mm (4.9 x 2.5 x 1.3″) and weighs 230 g (0.51 lb / 8.11 oz) (including batteries). Olympus TG-860 has external dimensions of 110 x 64 x 28 mm (5.12 x 2.52 x 1.1″) and weighs 224 g (0.49 lb / 7.90 oz) (including batteries).
