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 1D C 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 1D C has external dimensions of 158 x 164 x 83 mm (6.22 x 6.46 x 3.27″) and weighs 1500 g (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Canon 1D C. Ricoh G900 is clearly the smaller of the two cameras. Its body is 40mm narrower, 98mm shorter and 50mm thinner than Canon 1D C. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Canon 1D C doesn't. Once you put a lens on 1D C, its thickness will increase significantly.
Here is the back view size comparison of Ricoh G900 and Canon 1D C.
Now lets look at the top view comparison of Ricoh G900 and Canon 1D C.
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 (1253g ) than the Canon 1D C 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 1D C, the total kit will weigh much higher.
LCD Screen Size and Features
Canon 1D C's 3.20" LCD screen is slightly larger than Ricoh G900's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
