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-T10 and Olympus E-M1 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T10 has external dimensions of 118 x 83 x 41 mm (4.65 x 3.27 x 1.61″) and weighs 381 g (0.84 lb / 13.44 oz) (including batteries). Olympus E-M1 has external dimensions of 130 x 94 x 63 mm (5.13 x 3.68 x 2.48″) and weighs 497 g (1.10 lb / 17.53 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T10 and the Olympus E-M1. Fujifilm X-T10 is clearly the smaller of the two cameras. Its body is 12mm narrower, 11mm shorter and 22mm thinner than Olympus E-M1.
Here is the back view size comparison of the Fujifilm X-T10 and Olympus E-M1.
Now lets look at the top view comparison of Fujifilm X-T10 and Olympus E-M1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T10 is significantly lighter (116g ) than the Olympus E-M1 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 Fujifilm X-T10 has an APS-C sized sensor and Olympus E-M1 has a smaller Four Thirds sensor, Olympus E-M1's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-T10 lenses.
