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 R100 and Fujifilm X-A7 side-by-side from the front, back and top in their relative dimensions. Canon R100 has external dimensions of 116 x 86 x 69 mm (4.57 x 3.39 x 2.72″) and weighs 356 g (0.78 lb / 12.56 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 R100 and the Fujifilm X-A7. Fujifilm X-A7 is 18mm shorter and 28mm thinner than Canon R100 but it is also 3mm wider.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A7 is 36g lighter than the Canon R100 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 R100 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.
Weather Sealing
Unfortunately neither the Canon EOS R100 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.

LCD Screen Size and Features
Fujifilm X-A7's 3.50" LCD screen is slightly larger than Canon R100's 3″ screen.
Moreover, Fujifilm X-A7 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Canon R100 has a fixed type screen which provides almost no flexibility in shooting positions compared to X-A7.
