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 Sony a5100 and Fujifilm X-A7 side-by-side from the front, back and top in their relative dimensions. Sony a5100 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 283 g (0.62 lb / 9.98 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 Sony a5100 and the Fujifilm X-A7. Sony a5100 is clearly the smaller of the two cameras. Its body is 9mm narrower, 5mm shorter and 5mm thinner than Fujifilm X-A7.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony a5100 is 37g lighter than the Fujifilm X-A7 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 Sony a5100 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 Sony Alpha a5100 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.
