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 Sony W830 and Canon ELPH 190 IS side-by-side from the front, back and top in their relative dimensions. Sony W830 has external dimensions of 93 x 52 x 23 mm (3.66 x 2.05 x 0.91″) and weighs 122 g (0.27 lb / 4.30 oz) (including batteries).
