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 A6400 and Fujifilm X-T100 side-by-side from the front, back and top in their relative dimensions. Sony A6400 has external dimensions of 120 x 67 x 60 mm (4.72 x 2.64 x 2.36″) and weighs 403 g (0.89 lb / 14.22 oz) (including batteries). 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6400 is 45g 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 Sony A6400 and Fujifilm X-T100 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
With its weather-sealed body, we believe that the A6400 has a big advantage over the X-T100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A6400 and Fujifilm X-T100's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
