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 Panasonic ZS20 and Leica V-Lux 40 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS20 has external dimensions of 105 x 59 x 28 mm (4.13 x 2.32 x 1.1″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS20 is 4g lighter than the Leica V-Lux 40 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS20 (Lumix DMC-TZ30) 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. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic ZS20 and Leica V-Lux 40's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
