Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Sony RX100 VI and Nikon 1 J5 side-by-side from the front, back and top in their relative dimensions. Sony RX100 VI has external dimensions of 102 x 58 x 43 mm (4.02 x 2.28 x 1.69″) and weighs 301 g (0.66 lb / 10.62 oz) (including batteries). Nikon 1 J5 has external dimensions of 98 x 60 x 32 mm (3.86 x 2.36 x 1.26″) and weighs 231 g (0.51 lb / 8.15 oz) (including batteries).
Below you can see the front-view size comparison of the Sony RX100 VI and the Nikon 1 J5. Nikon 1 J5 is 4mm narrower and 11mm thinner than Sony RX100 VI but it is also 2mm taller. As you can tell, actually this is not a fair size comparison since Sony RX100 VI has a built-in lens but Nikon 1 J5 doesn't. Once you put a lens on J5, its thickness will increase significantly.
Here is the back view size comparison of the Sony RX100 VI and Nikon 1 J5.
Now lets look at the top view comparison of Sony RX100 VI and Nikon 1 J5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J5 is significantly lighter (70g ) than the Sony RX100 VI which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on J5, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 VI nor Nikon 1 J5 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
