Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Sony A7S and Ricoh GR Digital III side-by-side from the front, back and top in their relative dimensions. Sony A7S has external dimensions of 127 x 94 x 48 mm (5 x 3.7 x 1.89″) and weighs 489 g (1.08 lb / 17.25 oz) (including batteries). Ricoh GR Digital III has external dimensions of 109 x 59 x 26 mm (4.29 x 2.32 x 1.02″) and weighs 208 g (0.46 lb / 7.34 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Ricoh GR Digital III. Ricoh GR Digital III is clearly the smaller of the two cameras. Its body is 18mm narrower, 35mm shorter and 22mm thinner than Sony A7S. As you can tell, actually this is not a fair size comparison since Ricoh GR Digital III has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh GR Digital III is significantly lighter (281g ) than the Sony A7S 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, the total kit will weigh much higher.
Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over GR Digital III which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Ricoh GR Digital III's LCD screens has the same diagonal size of 3.
On the other hand, Sony A7S 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 Ricoh GR Digital III has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
Sony A7S has a 12.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Ricoh GR Digital III has a 10.0MP 1/1.7" (7.44 x 5.58 mm ) sized CCD sensor and features GR engine III processor.
