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 Typ 109 and Panasonic LX100 side-by-side from the front, back and top in their relative dimensions. Leica D-Lux Typ 109 has external dimensions of 118 x 66 x 55 mm (4.65 x 2.6 x 2.17″) and weighs 405 g (0.89 lb / 14.29 oz) (including batteries). Panasonic LX100 has external dimensions of 115 x 66 x 55 mm (4.53 x 2.6 x 2.17″) and weighs 393 g (0.87 lb / 13.86 oz) (including batteries).
Below you can see the front-view size comparison of the Leica D-Lux Typ 109 and the Panasonic LX100.
Here is the back view size comparison of the Leica D-Lux Typ 109 and Panasonic LX100.
Now lets look at the top view comparison of Leica D-Lux Typ 109 and Panasonic LX100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic LX100 is 12g lighter than the Leica D-Lux Typ 109 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Leica D-Lux Typ 109 nor Panasonic Lumix DMC-LX100 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 D-Lux Typ 109 and Panasonic LX100'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.
