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 Canon G1 X III and Nikon 1 J5 side-by-side from the front, back and top in their relative dimensions. Canon G1 X III has external dimensions of 115 x 78 x 51 mm (4.53 x 3.07 x 2.01″) and weighs 399 g (0.88 lb / 14.07 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 Canon G1 X III and Nikon 1 J5. Nikon 1 J5 is clearly the smaller of the two cameras. Its body is 17mm narrower, 18mm shorter and 19mm thinner than Canon G1 X III. As you can tell, actually this is not a fair size comparison since Canon G1 X III 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 Canon G1 X III and Nikon 1 J5.
Now lets look at the top view comparison of Canon G1 X III 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 (168g ) than the Canon G1 X III 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.
With its weather sealed body, we believe that G1 X III has a big advantage over J5 which doesn't provide any kind of environmental sealing.
