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 S5 and Leica Q side-by-side from the front, back and top in their relative dimensions. Panasonic S5 has external dimensions of 133 x 97 x 82 mm (5.24 x 3.82 x 3.23″) and weighs 714 g (1.57 lb) (including batteries). Leica Q has external dimensions of 130 x 80 x 93 mm (5.12 x 3.15 x 3.66″) and weighs 640 g (1.41 lb / 22.58 oz) (including batteries).
Below you can see the front view size comparison of Panasonic S5 and Leica Q. Leica Q is 3mm narrower and 17mm shorter than Panasonic S5 but it is also 11mm thicker. As you can tell, actually this is not a fair size comparison since Leica Q has a built-in lens but Panasonic S5 doesn't. Once you put a lens on S5, its thickness will increase significantly.
Here is the back view size comparison of Panasonic S5 and Leica Q.
Now lets look at the top view comparison of Panasonic S5 and Leica Q.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Leica Q is 74g lighter than the Panasonic S5 but we don't think this will make a significant difference.
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 S5, the total kit will weigh much higher.
With its weather sealed body, we believe that S5 has a big advantage over Q Typ 116 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic S5 and Leica Q's LCD screens has the same diagonal size of 3".
On the other hand, Panasonic S5 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. Leica Q's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S5.
