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 Panasonic G9 and Leica M-Monochrom side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Leica M-Monochrom has external dimensions of 139 x 80 x 37 mm (5.47 x 3.15 x 1.46″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).
Below you can see the front view size comparison of Panasonic G9 and Leica M-Monochrom. Leica M-Monochrom is 17mm shorter and 55mm thinner than Panasonic G9 but it is also 2mm wider.
Here is the back view size comparison of Panasonic G9 and Leica M-Monochrom.
Now lets look at the top view comparison of Panasonic G9 and Leica M-Monochrom.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Leica M-Monochrom is 58g lighter than the Panasonic G9 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Leica M-Monochrom has a Full frame sensor and Panasonic G9 has a smaller Four Thirds sensor, Panasonic G9's lenses for a similar focal length and aperture will generally be lighter and smaller than the Leica M-Monochrom lenses.
With its weather sealed body, we believe that G9 has a big advantage over M-Monochrom which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic G9's 3.00" LCD screen is slightly larger than Leica M-Monochrom's 2.5 screen.
Moreover, Panasonic G9 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Leica M-Monochrom has a fixed type screen which provides almost no flexibility in shooting positions compared to G9.
