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 4000D and Ricoh WG-4 side-by-side from the front, back and top in their relative dimensions. Canon 4000D has external dimensions of 129 x 102 x 77 mm (5.08 x 4.02 x 3.03″) and weighs 436 g (0.96 lb / 15.38 oz) (including batteries). Ricoh WG-4 has external dimensions of 124 x 64 x 33 mm (4.88 x 2.52 x 1.3″) and weighs 230 g (0.51 lb / 8.11 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 4000D and the Ricoh WG-4. Ricoh WG-4 is clearly the smaller of the two cameras. Its body is 5mm narrower, 38mm shorter and 44mm thinner than Canon 4000D. As you can tell, actually this is not a fair size comparison since Ricoh WG-4 has a built-in lens but Canon 4000D doesn't. Once you put a lens on 4000D, its thickness will increase significantly.
Here is the back view size comparison of the Canon 4000D and Ricoh WG-4.
Now lets look at the top view comparison of Canon 4000D and Ricoh WG-4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-4 is significantly lighter (206g ) than the Canon 4000D 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 4000D, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the WG-4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the 4000D.
LCD Screen Size and Features
Ricoh WG-4's 3.00" LCD screen is slightly larger than Canon 4000D's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
