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 Olympus E-M10 IV and Canon R3 side-by-side from the front, back and top in their relative dimensions. Olympus E-M10 IV has external dimensions of 122 x 84 x 49 mm (4.8 x 3.31 x 1.93″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries). Canon R3 has external dimensions of 150 x 143 x 87 mm (5.91 x 5.63 x 3.43″) and weighs 1015 g (2.24 lb / 35.80 oz) (including batteries).
Below you can see the front view size comparison of Olympus E-M10 IV and Canon R3. Olympus E-M10 IV is clearly the smaller of the two cameras. Its body is 28mm narrower, 59mm shorter and 38mm thinner than Canon R3.
Here is the back view size comparison of Olympus E-M10 IV and Canon R3.
Now lets look at the top view comparison of Olympus E-M10 IV and Canon R3.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus E-M10 IV is significantly lighter (632g ) than the Canon R3 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Canon R3 has a Full frame sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon R3 lenses.
Thanks to the weather sealed body of R3, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to E-M10 IV.
