Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G100 is significantly lighter (663g ) than the Canon R3 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 have to also take into account the lenses that you will be using with these bodies. Since Canon R3 has a Full frame sensor and Panasonic G100 has a smaller Four Thirds sensor, Panasonic G100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon R3 lenses.
Weather Sealing
Thanks to the weather sealed body of R3, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to G100.
