Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G3 is 47g lighter than the Olympus E-M10 IV 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 both Olympus E-M10 IV and Panasonic G3 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.
Weather Sealing
Unfortunately neither Olympus OM-D E-M10 IV nor Panasonic Lumix DMC-G3 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
