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 Panasonic S5 and Ricoh G900 side-by-side from the front, back and top in their relative dimensions. Panasonic S5 has external dimensions of 133 x 97 x 82 mm (5.24 x 3.82 x 3.23″) and weighs 714 g (1.57 lb) (including batteries). 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).
Below you can see the front view size comparison of Panasonic S5 and Ricoh G900. Ricoh G900 is clearly the smaller of the two cameras. Its body is 15mm narrower, 31mm shorter and 49mm thinner than Panasonic S5. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic S5 doesn't. Once you put a lens on S5, its thickness will increase significantly.
Here is the back view size comparison of Panasonic S5 and Ricoh G900.
Now lets look at the top view comparison of Panasonic S5 and Ricoh G900.
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 (467g ) than the Panasonic S5 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 S5, the total kit will weigh much higher.
LCD Screen Size and Features
Panasonic S5 and Ricoh G900's LCD screens has the same diagonal size of 3.00".
On the other hand, Panasonic S5 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Ricoh G900's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S5.
