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 Canon SL2 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). Canon SL2 has external dimensions of 122 x 93 x 70 mm (4.8 x 3.66 x 2.76″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Canon SL2. Ricoh G900 is clearly the smaller of the two cameras. Its body is 4mm narrower, 27mm shorter and 37mm thinner than Canon SL2. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Canon SL2 doesn't. Once you put a lens on SL2, its thickness will increase significantly.
Here is the back view size comparison of Ricoh G900 and Canon SL2.
Now lets look at the top view comparison of Ricoh G900 and Canon SL2.
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 (206g ) than the Canon SL2 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 SL2, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh G900 and Canon SL2's LCD screens has the same diagonal size of 3".
On the other hand, Canon SL2 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 SL2.
