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 Fujifilm X-T1 IR and Fujifilm X30 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 X30 has external dimensions of 119 x 72 x 60 mm (4.69 x 2.83 x 2.36″) and weighs 423 g (0.93 lb / 14.92 oz) (including batteries).
Below you can see the front view size comparison of Fujifilm X-T1 IR and Fujifilm X30. Fujifilm X30 is 10mm narrower and 18mm shorter than Fujifilm X-T1 IR but it is also 13mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm X30 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 Fujifilm X-T1 IR and Fujifilm X30.
Now lets look at the top view comparison of Fujifilm X-T1 IR and Fujifilm X30.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X30 is 17g lighter than the Fujifilm X-T1 IR 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-T1 IR, the total kit will weigh much higher.
With its weather sealed body, we believe that X-T1 IR has a big advantage over X30 which doesn't provide any kind of environmental sealing.
