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-T100 and Nikon Z5 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T100 has external dimensions of 121 x 83 x 47 mm (4.76 x 3.27 x 1.85″) and weighs 448 g (0.99 lb / 15.80 oz) (including batteries). Nikon Z5 has external dimensions of 134 x 101 x 70 mm (5.28 x 3.98 x 2.76″) and weighs 675 g (1.49 lb / 23.81 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T100 and the Nikon Z5. Fujifilm X-T100 is clearly the smaller of the two cameras. Its body is 13mm narrower, 18mm shorter and 23mm thinner than Nikon Z5.
Here is the back view size comparison of the Fujifilm X-T100 and Nikon Z5.
Now lets look at the top view comparison of Fujifilm X-T100 and Nikon Z5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T100 is significantly lighter (227g ) than the Nikon Z5 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 Nikon Z5 has a Full frame sensor and Fujifilm X-T100 has a smaller APS-C sensor, Fujifilm X-T100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon Z5 lenses.
Weather Sealing
Thanks to the weather-sealed body of the Z5, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the X-T100.
LCD Screen Size and Features
Nikon Z5's 3.20" LCD screen is slightly larger than Fujifilm X-T100's 3 screen.
