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 Sony A3000 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). Sony A3000 has external dimensions of 128 x 91 x 85 mm (5.04 x 3.58 x 3.35″) and weighs 411 g (0.91 lb / 14.50 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Sony A3000. Ricoh G900 is clearly the smaller of the two cameras. Its body is 10mm narrower, 25mm shorter and 52mm thinner than Sony A3000. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Sony A3000 doesn't. Once you put a lens on A3000, 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 (164g ) than the Sony A3000 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 A3000, the total kit will weigh much higher.
