Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G9 is 102g lighter than the Pentax K-5 II 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-5 II 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-5 II lenses.
Weather Sealing
Both G9 and K-5 II have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic G9 and Pentax K-5 II's LCD screens has the same diagonal size of 3.00".
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-5 II's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G9.
