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 Pentax K-50 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). Pentax K-50 has external dimensions of 130 x 97 x 71 mm (5.12 x 3.82 x 2.8″) and weighs 650 g (1.43 lb / 22.93 oz) (including batteries).
Below you can see the front view size comparison of Panasonic G9 and Pentax K-50. Panasonic G9 has the same height with Pentax K-50. On the other hand, with a width of 137mm, it is 7 wider and also with a thickness of 92mm, it is 21mm thicker than Pentax K-50.
Here is the back view size comparison of Panasonic G9 and Pentax K-50.
Now lets look at the top view comparison of Panasonic G9 and Pentax K-50.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax K-50 is 8g 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 Pentax K-50 has an APS-C sized 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 Pentax K-50 lenses.
Both G9 and K-50 have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic G9 and Pentax K-50's LCD screens has the same diagonal size of 3".
On the other hand, 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. Pentax K-50's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G9.
