Now lets look at the top view comparison of Sony A7C Mark II and Sony A7 IV.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A7C Mark II is significantly lighter (145g ) than the Sony A7 IV 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 also have to take into account the lenses that you will be using with these bodies. Since both Sony A7C Mark II and Sony A7 IV have the same Sony E lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Both the A7C II and the A7 IV have weather sealings in their bodies, making them resistant to water and dust.
