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 Sony A6100 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T100 has external dimensions of 121 x 83 x 47 mm (4.76 x 3.27 x 1.85″) and weighs 448 g (0.99 lb / 15.80 oz) (including batteries). Sony A6100 has external dimensions of 120 x 67 x 59 mm (4.72 x 2.64 x 2.32″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6100 is 52g lighter than the Fujifilm X-T100 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 Fujifilm X-T100 and Sony A6100 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 Sony Alpha a6100 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
