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-Pro2 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).

Here is the back view size comparison of the Sony a5100 and Fujifilm X-Pro2.
Now lets look at the top view comparison of Sony a5100 and Fujifilm X-Pro2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony a5100 is significantly lighter (212g ) than the Fujifilm X-Pro2 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 Sony a5100 and Fujifilm X-Pro2 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
Thanks to the weather-sealed body of the X-Pro2, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the a5100.
LCD Screen Size and Features
Sony a5100 and Fujifilm X-Pro2's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony a5100 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Fujifilm X-Pro2 has a fixed type screen which provides less flexibility in shooting positions compared to a5100.
