Ricoh G900 vs Olympus E-M5 II: Physical Specs and Body features Comparison

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 G900 and Olympus E-M5 II side-by-side from the front, back and top in their relative dimensions. Ricoh G900 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries). Olympus E-M5 II has external dimensions of 124 x 85 x 45 mm (4.88 x 3.35 x 1.77″) and weighs 469 g (1.03 lb / 16.54 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Olympus E-M5 II. Ricoh G900 is clearly the smaller of the two cameras. Its body is 6mm narrower, 19mm shorter and 12mm thinner than Olympus E-M5 II. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Olympus E-M5 II doesn't. Once you put a lens on E-M5 Mark II, 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 G900 is significantly lighter (222g ) than the Olympus E-M5 II 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-M5 Mark II, the total kit will weigh much higher.
