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 Casio EX-100 and Fujifilm X-E2 side-by-side from the front, back and top in their relative dimensions. Casio EX-100 has external dimensions of 119x67x50 mm and weighs 389 g (including batteries). Fujifilm X-E2 has external dimensions of 129 x 75 x 37 mm (5.08 x 2.95 x 1.46″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-100 and the Fujifilm X-E2. Casio EX-100 is 10mm narrower and 8mm shorter than Fujifilm X-E2 but it is also 13mm thicker. As you can tell, actually this is not a fair size comparison since Casio EX-100 has a built-in lens but Fujifilm X-E2 doesn't. Once you put a lens on X-E2, its thickness will increase significantly.
Here is the back view size comparison of the Casio EX-100 and Fujifilm X-E2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-E2 is 39g lighter than the Casio EX-100 but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on X-E2, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Casio Exilim EX-100 nor Fujifilm X-E2 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Casio EX-100's 3.50" LCD screen is slightly larger than Fujifilm X-E2's 3" screen.
In addition to the size advantage, Casio EX-100 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Fujifilm X-E2 has a fixed type screen which provides less flexibility in shooting positions compared to EX-100.
