Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A7S II is 89g lighter than the Sony FX3 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 also have to take into account the lenses that you will be using with these bodies. Since both Sony FX3 and Sony A7S II have the same Sony E lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Both the FX3 and the A7S II have weather sealings in their bodies, making them resistant to water and dust.
