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 G900 and Panasonic G6 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 G6 has external dimensions of 122 x 85 x 71 mm (4.8 x 3.35 x 2.8″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh G900 and the Panasonic G6. Ricoh G900 is clearly the smaller of the two cameras. Its body is 4mm narrower, 19mm shorter and 38mm thinner than Panasonic G6. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic G6 doesn't. Once you put a lens on G6, its thickness will increase significantly.
Now lets look at the top view comparison of Ricoh G900 and Panasonic G6.
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 (143g ) than the Panasonic G6 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 G6, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the G900, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G6.
LCD Screen Size and Features
Ricoh G900 and Panasonic G6's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic G6 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 G6.
