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 Canon 50D and Ricoh WG-M1 side-by-side from the front, back and top in their relative dimensions. Canon 50D has external dimensions of 146 x 108 x 74 mm (5.75 x 4.25 x 2.91″) and weighs 822 g (1.81 lb / 29.00 oz) (including batteries). Ricoh WG-M1 has external dimensions of 66 x 43 x 89 mm (2.6 x 1.69 x 3.5″) and weighs 190 g (0.42 lb / 6.70 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 50D and the Ricoh WG-M1. Ricoh WG-M1 is 80mm narrower and 65mm shorter than Canon 50D but it is also 15mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh WG-M1 has a built-in lens but Canon 50D doesn't. Once you put a lens on 50D, its thickness will increase significantly.
Here is the back view size comparison of the Canon 50D and Ricoh WG-M1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-M1 is significantly lighter (632g ) than the Canon 50D 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 50D, the total kit will weigh much higher.

LCD Screen Size and Features
Canon 50D's 3.00" LCD screen is slightly larger than Ricoh WG-M1's 1.5 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
