Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic LX10 and Sony RX100 V side-by-side from the front, back and top in their relative dimensions. Panasonic LX10 has external dimensions of 106 x 60 x 42 mm (4.17 x 2.36 x 1.65″) and weighs 310 g (0.68 lb / 10.93 oz) (including batteries). Sony RX100 V has external dimensions of 102 x 58 x 41 mm (4.02 x 2.28 x 1.61″) and weighs 299 g (0.66 lb / 10.55 oz) (including batteries).
Below you can see the front view size comparison of Panasonic LX10 and Sony RX100 V. Sony RX100 V is clearly the smaller of the two cameras. Its body is 4mm narrower, 2mm shorter and 1mm thinner than Panasonic LX10.
Now lets look at the top view comparison of Panasonic LX10 and Sony RX100 V.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony RX100 V is 11g lighter than the Panasonic LX10 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-LX10 (Lumix DMC-LX15) nor Sony Cyber-shot DSC-RX100 V provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
