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-T10 and Olympus SZ-15 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T10 has external dimensions of 118 x 83 x 41 mm (4.65 x 3.27 x 1.61″) and weighs 381 g (0.84 lb / 13.44 oz) (including batteries). Olympus SZ-15 has external dimensions of and weighs 250 g (0.55 lb / 8.82 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T10 and the Olympus SZ-15. Olympus SZ-15 is clearly the smaller of the two cameras. Its body is 10mm narrower, 13mm shorter and 1mm thinner than Fujifilm X-T10. As you can tell, actually this is not a fair size comparison since Olympus SZ-15 has a built-in lens but Fujifilm X-T10 doesn't. Once you put a lens on X-T10, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm X-T10 and Olympus SZ-15.
Now lets look at the top view comparison of Fujifilm X-T10 and Olympus SZ-15.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-15 is significantly lighter (131g ) than the Fujifilm X-T10 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-T10, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Fujifilm X-T10 nor Olympus SZ-15 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
Fujifilm X-T10 and Olympus SZ-15's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-T10 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 Olympus SZ-15 has a fixed type screen which provides less flexibility in shooting positions compared to X-T10.
