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 Ricoh GXR Mount A12 and Olympus E-M10 II side-by-side from the front, back and top in their relative dimensions. Ricoh GXR Mount A12 has external dimensions of 120 x 70 x 45 mm (4.72 x 2.76 x 1.77″) and weighs 370 g (0.82 lb / 13.05 oz) (including batteries). Olympus E-M10 II has external dimensions of 120 x 83 x 47 mm (4.72 x 3.27 x 1.85″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh GXR Mount A12 and the Olympus E-M10 II. Ricoh GXR Mount A12 has the same height with Olympus E-M10 II. On the other hand, with a width of 70mm, it is 13 narrower and also with a thickness of 45mm, it is 2mm thinner than Olympus E-M10 II. As you can tell, actually this is not a fair size comparison since Ricoh GXR Mount A12 has a built-in lens but Olympus E-M10 II doesn't. Once you put a lens on E-M10 II, its thickness will increase significantly.
Now lets look at the top view comparison of Ricoh GXR Mount A12 and Olympus E-M10 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh GXR Mount A12 is 20g lighter than the Olympus E-M10 II but we don't think this will make a significant difference.
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 E-M10 II, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Ricoh GXR Mount A12 nor Olympus OM-D E-M10 II provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Ricoh GXR Mount A12 and Olympus E-M10 II's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M10 II 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 GXR Mount A12 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 II.
