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-T1 and Olympus E-M1 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T1 has external dimensions of 129 x 90 x 47 mm (5.08 x 3.54 x 1.84″) and weighs 440 g (0.97 lb / 15.52 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-T1 and the Olympus E-M1. Fujifilm X-T1 is clearly the smaller of the two cameras. Its body is 1mm narrower, 4mm shorter and 16mm thinner than Olympus E-M1.
Here is the back view size comparison of the Fujifilm X-T1 and Olympus E-M1.
Now lets look at the top view comparison of Fujifilm X-T1 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-T1 is 57g lighter than the Olympus E-M1 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 Fujifilm X-T1 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-T1 lenses.
Weather Sealing
Both the X-T1 and the E-M1 have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Fujifilm X-T1 and Olympus E-M1'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.
