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 X100T and Sony A390 side-by-side from the front, back and top in their relative dimensions. 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). Sony A390 has external dimensions of 128 x 97 x 86 mm (5.04 x 3.82 x 3.39″) and weighs 549 g (1.21 lb / 19.37 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X100T and the Sony A390. Fujifilm X100T is clearly the smaller of the two cameras. Its body is 1mm narrower, 23mm shorter and 34mm thinner than Sony A390. As you can tell, actually this is not a fair size comparison since Fujifilm X100T has a built-in lens but Sony A390 doesn't. Once you put a lens on A390, its thickness will increase significantly.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X100T is significantly lighter (109g ) than the Sony A390 which may become a big advantage especially on long walking trips.
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 A390, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Fujifilm X100T nor Sony Alpha DSLR-A390 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
