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-S10 and Fujifilm X-E4 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-S10 has external dimensions of 126 x 85 x 65 mm (4.96 x 3.35 x 2.56″) and weighs 465 g (1.03 lb / 16.40 oz) (including batteries). Fujifilm X-E4 has external dimensions of 121 x 73 x 33 mm (4.76 x 2.87 x 1.3″) and weighs 364 g (0.80 lb / 12.84 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-S10 and the Fujifilm X-E4. Fujifilm X-E4 is clearly the smaller of the two cameras. Its body is 5mm narrower, 12mm shorter and 32mm thinner than Fujifilm X-S10.
Here is the back view size comparison of the Fujifilm X-S10 and Fujifilm X-E4.
Now lets look at the top view comparison of Fujifilm X-S10 and Fujifilm X-E4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-E4 is significantly lighter (101g ) than the Fujifilm X-S10 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 Fujifilm X-S10 and Fujifilm X-E4 have the same Fujifilm X lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Fujifilm X-S10 nor Fujifilm X-E4 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
