Ricoh G900 vs Nikon D7100: 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 Nikon D7100 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). Nikon D7100 has external dimensions of 136 x 107 x 76 mm (5.35 x 4.21 x 2.99″) and weighs 765 g (1.69 lb / 26.98 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Nikon D7100. Ricoh G900 is clearly the smaller of the two cameras. Its body is 18mm narrower, 41mm shorter and 43mm thinner than Nikon D7100. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Nikon D7100 doesn't. Once you put a lens on D7100, 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 (518g ) than the Nikon D7100 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 D7100, the total kit will weigh much higher.
