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 G900 and Samsung Galaxy NX 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). Samsung Galaxy NX has external dimensions of 137 x 101 x 26 mm (5.39 x 3.98 x 1.02″) and weighs 495 g (1.09 lb / 17.46 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh G900 and the Samsung Galaxy NX. Ricoh G900 is 19mm narrower and 35mm shorter than Samsung Galaxy NX but it is also 7mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Samsung Galaxy NX doesn't. Once you put a lens on Galaxy NX, its thickness will increase significantly.
Here is the back view size comparison of the Ricoh G900 and Samsung Galaxy NX.
Now lets look at the top view comparison of Ricoh G900 and Samsung Galaxy NX.
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 (248g ) than the Samsung Galaxy NX 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 Galaxy NX, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the G900, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the Galaxy NX.
LCD Screen Size and Features
Samsung Galaxy NX's 4.80" LCD screen is slightly larger than Ricoh G900's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
