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 Leica C 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). Leica C has external dimensions of 103 x 63 x 28 mm (4.06 x 2.48 x 1.1″) and weighs 195 g (0.43 lb / 6.88 oz) (including batteries).
Below you can see the front-view size comparison of the Leica D-Lux Typ 109 and the Leica C. Leica C is clearly the smaller of the two cameras. Its body is 15mm narrower, 3mm shorter and 27mm thinner than Leica D-Lux Typ 109.
Here is the back view size comparison of the Leica D-Lux Typ 109 and Leica C.
Now lets look at the top view comparison of Leica D-Lux Typ 109 and Leica C.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica C is significantly lighter (210g ) than the Leica D-Lux Typ 109 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Leica D-Lux Typ 109 nor Leica C (Typ112) 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
Leica D-Lux Typ 109 and Leica C'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.
