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 A7S III and Ricoh GXR A16 24-85mm side-by-side from the front, back and top in their relative dimensions. Sony A7S III has external dimensions of 129 x 97 x 81 mm (5.08 x 3.82 x 3.19″) and weighs 699 g (1.54 lb / 24.66 oz) (including batteries). Ricoh GXR A16 24-85mm has external dimensions of 114 x 75 x 93 mm (4.49 x 2.95 x 3.66″) and weighs 550 g (including batteries).
Below you can see the front-view size comparison of the Sony A7S III and the Ricoh GXR A16 24-85mm. Ricoh GXR A16 24-85mm is 15mm narrower and 22mm shorter than Sony A7S III but it is also 12mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh GXR A16 24-85mm has a built-in lens but Sony A7S III doesn't. Once you put a lens on A7S III, its thickness will increase significantly.
Here is the back view size comparison of the Sony A7S III and Ricoh GXR A16 24-85mm.
Now lets look at the top view comparison of Sony A7S III and Ricoh GXR A16 24-85mm.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh GXR A16 24-85mm is significantly lighter (149g ) than the Sony A7S 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 A7S III, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the A7S III has a big advantage over the GXR A16 24-85mm F3.5-5.5 which doesn't provide any kind of environmental sealing.
