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 Sony T90 and Fujifilm X-A1 side-by-side from the front, back and top in their relative dimensions. Sony T90 has external dimensions of 94 x 57 x 15 mm (3.7 x 2.24 x 0.59″) and weighs 148 g (0.33 lb / 5.22 oz) (including batteries). Fujifilm X-A1 has external dimensions of 117 x 67 x 39 mm (4.6 x 2.62 x 1.54″) and weighs 330 g (0.73 lb / 11.64 oz) (including batteries).
Below you can see the front-view size comparison of the Sony T90 and the Fujifilm X-A1. Sony T90 is clearly the smaller of the two cameras. Its body is 23mm narrower, 10mm shorter and 24mm thinner than Fujifilm X-A1. As you can tell, actually this is not a fair size comparison since Sony T90 has a built-in lens but Fujifilm X-A1 doesn't. Once you put a lens on X-A1, its thickness will increase significantly.
Here is the back view size comparison of the Sony T90 and Fujifilm X-A1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony T90 is significantly lighter (182g ) than the Fujifilm X-A1 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 X-A1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-T90 nor Fujifilm X-A1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony T90 and Fujifilm X-A1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-A1 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 Sony T90 has a fixed type screen which provides less flexibility in shooting positions compared to X-A1.
