Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Olympus E-M5 III and Fujifilm GFX 100 side-by-side from the front, back and top in their relative dimensions.
Below you can see the front view size comparison of Olympus E-M5 III and Fujifilm GFX 100. Olympus E-M5 III is clearly the smaller of the two cameras. Its body is 31mm narrower, 59mm shorter and 25mm thinner than Fujifilm GFX 100.
Here is the back view size comparison of Olympus E-M5 III and Fujifilm GFX 100.
Now lets look at the top view comparison of Olympus E-M5 III and Fujifilm GFX 100.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
