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 C-Lux and Panasonic ZS100 side-by-side from the front, back and top in their relative dimensions. Leica C-Lux has external dimensions of 113 x 67 x 46 mm (4.45 x 2.64 x 1.81″) and weighs 340 g (0.75 lb / 11.99 oz) (including batteries). Panasonic ZS100 has external dimensions of 111 x 65 x 44 mm (4.37 x 2.56 x 1.73″) and weighs 312 g (0.69 lb / 11.01 oz) (including batteries).
Below you can see the front-view size comparison of the Leica C-Lux and the Panasonic ZS100. Panasonic ZS100 is clearly the smaller of the two cameras. Its body is 2mm narrower, 2mm shorter and 2mm thinner than Leica C-Lux.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS100 is 28g lighter than the Leica C-Lux but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Leica C-Lux nor Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Leica C-Lux and Panasonic ZS100'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.
