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 Leica V-Lux 40 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). Leica V-Lux 40 has external dimensions of 105 x 59 x 28 mm (4.13 x 2.32 x 1.1″) and weighs 210 g (0.46 lb / 7.41 oz) (including batteries).
Below you can see the front-view size comparison of the Leica V-Lux 20 and the Leica V-Lux 40. Leica V-Lux 40 is 1mm shorter and 5mm thinner than Leica V-Lux 20 but it is also 2mm wider.
Here is the back view size comparison of the Leica V-Lux 20 and Leica V-Lux 40.
Now lets look at the top view comparison of Leica V-Lux 20 and Leica V-Lux 40.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica V-Lux 40 is 8g lighter than the Leica V-Lux 20 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Leica V-Lux 20 nor Leica V-Lux 40 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
