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 Sony W570 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W570 is 6g lighter than the Sony W830 but we don't think this will make a significant difference.
