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-6 and Sony A580 side-by-side from the front, back and top in their relative dimensions. Ricoh WG-6 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 246 g (0.54 lb / 8.68 oz) (including batteries). Sony A580 has external dimensions of 137 x 104 x 84 mm (5.39 x 4.09 x 3.31″) and weighs 599 g (1.32 lb / 21.13 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh WG-6 and the Sony A580. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 19mm narrower, 38mm shorter and 51mm thinner than Sony A580. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Sony A580 doesn't. Once you put a lens on A580, its thickness will increase significantly.
Here is the back view size comparison of the Ricoh WG-6 and Sony A580.
Now lets look at the top view comparison of Ricoh WG-6 and Sony A580.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-6 is significantly lighter (353g ) than the Sony A580 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 A580, the total kit will weigh much higher.
Thanks to the weather-sealed body of the WG-6, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the A580.
LCD Screen Size and Features
Ricoh WG-6 and Sony A580's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony A580 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-6 has a fixed type screen which provides less flexibility in shooting positions compared to A580.
