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 NEX-5T 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 NEX-5T has external dimensions of 111 x 59 x 39 mm (4.36 x 2.31 x 1.53″) and weighs 276 g (0.61 lb / 9.74 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Sony NEX-5T. Sony NEX-5T is 7mm narrower and 7mm shorter than Ricoh G900 but it is also 6mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Sony NEX-5T doesn't. Once you put a lens on NEX-5T, its thickness will increase significantly.
Now lets look at the top view comparison of Ricoh G900 and Sony NEX-5T.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh G900 is 29g lighter than the Sony NEX-5T but we don't think this will make a significant difference.
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 NEX-5T, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh G900 and Sony NEX-5T's LCD screens has the same diagonal size of 3.00".
On the other hand, Sony NEX-5T 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 G900 has a fixed type screen which provides less flexibility in shooting positions compared to NEX-5T.
