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 M100 and Fujifilm X-T20 side-by-side from the front, back and top in their relative dimensions. Canon M100 has external dimensions of 108 x 67 x 35 mm (4.25 x 2.64 x 1.38″) and weighs 302 g (0.67 lb / 10.65 oz) (including batteries). Fujifilm X-T20 has external dimensions of 118 x 83 x 41 mm (4.65 x 3.27 x 1.61″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries).
Below you can see the front-view size comparison of the Canon M100 and the Fujifilm X-T20. Canon M100 is clearly the smaller of the two cameras. Its body is 10mm narrower, 16mm shorter and 6mm thinner than Fujifilm X-T20.
Here is the back view size comparison of the Canon M100 and Fujifilm X-T20.
Now lets look at the top view comparison of Canon M100 and Fujifilm X-T20.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon M100 is significantly lighter (81g ) than the Fujifilm X-T20 which may become a big advantage especially on long walking trips.
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 M100 and Fujifilm X-T20 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Unfortunately neither the Canon EOS M100 nor Fujifilm X-T20 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
