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 Sony A6500 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). Sony A6500 has external dimensions of 120 x 67 x 53 mm (4.72 x 2.64 x 2.09″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries).
Below you can see the front view size comparison of Canon G1 X III and Sony A6500. Canon G1 X III is 5mm narrower and 2mm thinner than Sony A6500 but it is also 11mm taller. As you can tell, actually this is not a fair size comparison since Canon G1 X III has a built-in lens but Sony A6500 doesn't. Once you put a lens on A6500, its thickness will increase significantly.
Here is the back view size comparison of Canon G1 X III and Sony A6500.
Now lets look at the top view comparison of Canon G1 X III and Sony A6500.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G1 X III is 54g lighter than the Sony A6500 but we don't think this will make a significant difference.
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 A6500, the total kit will weigh much higher.
Both G1 X III and A6500 have weather sealings in their body, making them resistant to water and dust.
