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 RX100 V and Fujifilm X-T200 side-by-side from the front, back and top in their relative dimensions. Sony RX100 V has external dimensions of 102 x 58 x 41 mm (4.02 x 2.28 x 1.61″) and weighs 299 g (0.66 lb / 10.55 oz) (including batteries). Fujifilm X-T200 has external dimensions of 121 x 84 x 55 mm (4.76 x 3.31 x 2.17″) and weighs 370 g (0.82 lb / 13.05 oz) (including batteries).
Below you can see the front-view size comparison of the Sony RX100 V and the Fujifilm X-T200. Sony RX100 V is clearly the smaller of the two cameras. Its body is 19mm narrower, 26mm shorter and 14mm thinner than Fujifilm X-T200. As you can tell, actually this is not a fair size comparison since Sony RX100 V has a built-in lens but Fujifilm X-T200 doesn't. Once you put a lens on X-T200, its thickness will increase significantly.
Here is the back view size comparison of the Sony RX100 V and Fujifilm X-T200.
Now lets look at the top view comparison of Sony RX100 V and Fujifilm X-T200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony RX100 V is significantly lighter (71g ) than the Fujifilm X-T200 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-T200, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 V nor Fujifilm X-T200 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
