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 D-Lux 7 and Sigma DP2 Quattro side-by-side from the front, back and top in their relative dimensions. Leica D-Lux 7 has external dimensions of 118 x 66 x 64 mm (4.65 x 2.6 x 2.52″) and weighs 403 g (0.89 lb / 14.22 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sigma DP2 Quattro is 8g lighter than the Leica D-Lux 7 but we don't think this will make a significant difference.
