Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony RX100 III is significantly lighter (50g ) than the Leica C-Lux which may become a big advantage especially on long walking trips.
Unfortunately neither Leica C-Lux nor Sony Cyber-shot DSC-RX100 III provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

On the other hand, Sony RX100 III features a Tilting screen
