Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus E-M10 IV is significantly lighter (191g ) than the Olympus E-M1 II 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 both Olympus E-M10 IV and Olympus E-M1 II have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Thanks to the weather sealed body of E-M1 II, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to E-M10 IV.
