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 Panasonic GX85 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). Panasonic GX85 has external dimensions of 122 x 71 x 44 mm (4.8 x 2.8 x 1.73��) and weighs 426 g (0.94 lb / 15.03 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Panasonic GX85. Ricoh G900 is clearly the smaller of the two cameras. Its body is 4mm narrower, 5mm shorter and 11mm thinner than Panasonic GX85. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic GX85 doesn't. Once you put a lens on GX85, its thickness will increase significantly.
Here is the back view size comparison of Ricoh G900 and Panasonic GX85.
Now lets look at the top view comparison of Ricoh G900 and Panasonic GX85.
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 (179g ) than the Panasonic GX85 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 GX85, the total kit will weigh much higher.
Thanks to the weather sealed body of G900, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to GX85.
LCD Screen Size and Features
Ricoh G900 and Panasonic GX85's LCD screens has the same diagonal size of 3.00".
On the other hand, Panasonic GX85 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 GX85.
