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 Pentax Q-S1 and Panasonic GX7 side-by-side from the front, back and top in their relative dimensions. Pentax Q-S1 has external dimensions of 105 x 58 x 34 mm (4.13 x 2.28 x 1.34″) and weighs 203 g (0.45 lb / 7.16 oz) (including batteries). Panasonic GX7 has external dimensions of 123 x 71 x 55 mm (4.83 x 2.78 x 2.15″) and weighs 402 g (0.89 lb / 14.18 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Q-S1 and the Panasonic GX7. Pentax Q-S1 is clearly the smaller of the two cameras. Its body is 18mm narrower, 13mm shorter and 21mm thinner than Panasonic GX7.
Here is the back view size comparison of the Pentax Q-S1 and Panasonic GX7.
Now lets look at the top view comparison of Pentax Q-S1 and Panasonic GX7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Q-S1 is significantly lighter (199g ) than the Panasonic GX7 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies.
Weather Sealing
Unfortunately neither the Pentax Q-S1 nor Panasonic Lumix DMC-GX7 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
Pentax Q-S1 and Panasonic GX7's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GX7 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Pentax Q-S1 has a fixed type screen which provides less flexibility in shooting positions compared to GX7.
