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 WG-4 and Sony NEX-5T side-by-side from the front, back and top in their relative dimensions. Ricoh WG-4 has external dimensions of 124 x 64 x 33 mm (4.88 x 2.52 x 1.3″) and weighs 230 g (0.51 lb / 8.11 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 the Ricoh WG-4 and the Sony NEX-5T. Sony NEX-5T is 13mm narrower and 5mm shorter than Ricoh WG-4 but it is also 6mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh WG-4 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 WG-4 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 WG-4 is significantly lighter (46g ) than the Sony NEX-5T 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 NEX-5T, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the WG-4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the NEX-5T.
LCD Screen Size and Features
Ricoh WG-4 and Sony NEX-5T's LCD screens have the same diagonal size of 3.00 inches.
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 WG-4 has a fixed type screen which provides less flexibility in shooting positions compared to NEX-5T.
