Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A7 II is 51g lighter than the Sony A7 III 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 Sony A7 III and Sony A7 II have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
