Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony ZV-E1 is significantly lighter (233g ) than the Sony FX3 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 FX3 and Sony ZV-E1 have the same Sony E lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
