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 Ricoh WG-6 and Olympus E-M10 side-by-side from the front, back and top in their relative dimensions. Ricoh WG-6 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 246 g (0.54 lb / 8.68 oz) (including batteries). Olympus E-M10 has external dimensions of 119 x 82 x 46 mm (4.69 x 3.24 x 1.81″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front view size comparison of Ricoh WG-6 and Olympus E-M10. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 1mm narrower, 16mm shorter and 13mm thinner than Olympus E-M10. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Olympus E-M10 doesn't. Once you put a lens on E-M10, its thickness will increase significantly.
Here is the back view size comparison of Ricoh WG-6 and Olympus E-M10.
Now lets look at the top view comparison of Ricoh WG-6 and Olympus E-M10.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-6 is significantly lighter (150g ) than the Olympus E-M10 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 E-M10, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh WG-6 and Olympus E-M10's LCD screens has the same diagonal size of 3.00".
On the other hand, Olympus E-M10 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 WG-6 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10.
