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-A5 and Sony RX10 III side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A5 has external dimensions of 117 x 68 x 40 mm (4.61 x 2.68 x 1.57″) and weighs 361 g (0.80 lb / 12.73 oz) (including batteries). Sony RX10 III has external dimensions of 133 x 94 x 127 mm (5.24 x 3.7 x 5″) and weighs 1051 g (2.32 lb / 37.07 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-A5 and the Sony RX10 III. Fujifilm X-A5 is clearly the smaller of the two cameras. Its body is 16mm narrower, 26mm shorter and 87mm thinner than Sony RX10 III. As you can tell, actually this is not a fair size comparison since Sony RX10 III has a built-in lens but Fujifilm X-A5 doesn't. Once you put a lens on X-A5, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm X-A5 and Sony RX10 III.
Now lets look at the top view comparison of Fujifilm X-A5 and Sony RX10 III.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A5 is significantly lighter (690g ) than the Sony RX10 III 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-A5, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the RX10 III, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the X-A5.
