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 Canon M3 and Fujifilm X-A7 side-by-side from the front, back and top in their relative dimensions. Canon M3 has external dimensions of 111 x 68 x 44 mm (4.37 x 2.68 x 1.73″) and weighs 366 g (0.81 lb / 12.91 oz) (including batteries). Fujifilm X-A7 has external dimensions of 119 x 68 x 41 mm (4.69 x 1.5 x 1.61″) and weighs 320 g (0.71 lb / 11.29 oz) (including batteries).
Below you can see the front-view size comparison of the Canon M3 and the Fujifilm X-A7.
Here is the back view size comparison of the Canon M3 and Fujifilm X-A7.
Now lets look at the top view comparison of Canon M3 and Fujifilm X-A7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A7 is 46g lighter than the Canon M3 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Canon M3 and Fujifilm X-A7 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Unfortunately neither the Canon EOS M3 nor Fujifilm X-A7 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
