Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Leica V-Lux 20 and Panasonic ZS50 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Leica V-Lux 20 is 25g lighter than the Panasonic ZS50 but we don't think this will make a significant difference.
Unfortunately neither Leica V-Lux 20 nor Panasonic Lumix DMC-ZS50 (Lumix DMC-TZ70) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
