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-A3 and Sony A7 III side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A3 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 339 g (0.75 lb / 11.96 oz) (including batteries). Sony A7 III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 650 g (1.43 lb / 22.93 oz) (including batteries).

Now lets look at the top view comparison of Fujifilm X-A3 and Sony A7 III.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A3 is significantly lighter (311g ) than the Sony A7 III which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Sony A7 III has a Full frame sensor and Fujifilm X-A3 has a smaller APS-C sensor, Fujifilm X-A3's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7 III lenses.
