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 Fujifilm X-T100 and Canon M3 side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon M3 is significantly lighter (82g ) than the Fujifilm X-T100 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 Fujifilm X-T100 and Canon M3 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 Fujifilm X-T100 nor Canon EOS M3 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
