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 IR and Fujifilm X100T side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T1 IR has external dimensions of 129 x 90 x 47 mm (5.08 x 3.54 x 1.85″) and weighs 440 g (0.97 lb / 15.52 oz) (including batteries). Fujifilm X100T has external dimensions of 127 x 74 x 52 mm (5 x 2.91 x 2.05″) and weighs 440 g (0.97 lb / 15.52 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T1 IR and the Fujifilm X100T. Fujifilm X100T is 2mm narrower and 16mm shorter than Fujifilm X-T1 IR but it is also 5mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm X100T has a built-in lens but Fujifilm X-T1 IR doesn't. Once you put a lens on X-T1 IR, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm X-T1 IR and Fujifilm X100T.
Now lets look at the top view comparison of Fujifilm X-T1 IR and Fujifilm X100T.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T1 IR and Fujifilm X100T have exactly the same weight of 440g.
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-T1 IR, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the X-T1 IR has a big advantage over the X100T which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Fujifilm X-T1 IR and Fujifilm X100T's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-T1 IR features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Fujifilm X100T has a fixed type screen which provides less flexibility in shooting positions compared to X-T1 IR.
