Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A6500 is 50g lighter than the Sony A6600 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 A6600 and Sony A6500 have the same Sony E lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Both A6600 and A6500 have weather sealings in their body, making them resistant to water and dust.
