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 Leica V-Lux 20 and Pentax WG-1 GPS side-by-side from the front, back and top in their relative dimensions. Leica V-Lux 20 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). Pentax WG-1 GPS has external dimensions of 116 x 59 x 29 mm (4.55 x 2.3 x 1.12″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries).

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