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-T3 and Fujifilm X100V side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T3 has external dimensions of 133 x 93 x 59 mm (5.24 x 3.66 x 2.32″) and weighs 539 g (1.19 lb / 19.01 oz) (including batteries). Fujifilm X100V has external dimensions of 128 x 75 x 53 mm (5.04 x 2.95 x 2.09″) and weighs 478 g (1.05 lb / 16.86 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T3 and the Fujifilm X100V. Fujifilm X100V is clearly the smaller of the two cameras. Its body is 5mm narrower, 18mm shorter and 6mm thinner than Fujifilm X-T3. As you can tell, actually this is not a fair size comparison since Fujifilm X100V has a built-in lens but Fujifilm X-T3 doesn't. Once you put a lens on X-T3, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm X-T3 and Fujifilm X100V.
Now lets look at the top view comparison of Fujifilm X-T3 and Fujifilm X100V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X100V is 61g lighter than the Fujifilm X-T3 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-T3, the total kit will weigh much higher.
Weather Sealing
Both the X-T3 and the X100V have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Fujifilm X-T3 and Fujifilm X100V'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.
