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 Leica SL 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). Leica SL has external dimensions of 147 x 104 x 39 mm (5.79 x 4.09 x 1.54″) and weighs 847 g (1.87 lb / 29.88 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Leica SL. Ricoh G900 is clearly the smaller of the two cameras. Its body is 29mm narrower, 38mm shorter and 6mm thinner than Leica SL. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Leica SL doesn't. Once you put a lens on SL, its thickness will increase significantly.
Here is the back view size comparison of Ricoh G900 and Leica SL.
Now lets look at the top view comparison of Ricoh G900 and Leica SL.
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 (600g ) than the Leica SL 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 SL, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh G900 and Leica SL's LCD screens has the same diagonal size of 3.00".
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
