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 G9 and Leica X2 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 X2 has external dimensions of 124 x 69 x 52 mm (4.88 x 2.72 x 2.05″) and weighs 345 g (0.76 lb / 12.17 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G9 and the Leica X2. Leica X2 is clearly the smaller of the two cameras. Its body is 13mm narrower, 28mm shorter and 40mm thinner than Panasonic G9. As you can tell, actually this is not a fair size comparison since Leica X2 has a built-in lens but Panasonic G9 doesn't. Once you put a lens on G9, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic G9 and Leica X2.
Now lets look at the top view comparison of Panasonic G9 and Leica X2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica X2 is significantly lighter (313g ) than the Panasonic G9 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G9, the total kit will weigh much higher.
With its weather-sealed body, we believe that the G9 has a big advantage over the X2 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 X2's 2.7 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 X2 has a fixed type screen which provides almost no flexibility in shooting positions compared to G9.
