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 R100 and Canon R8 side-by-side from the front, back and top in their relative dimensions. Canon R100 has external dimensions of 116 x 86 x 69 mm (4.57 x 3.39 x 2.72″) and weighs 356 g (0.78 lb / 12.56 oz) (including batteries). Canon R8 has external dimensions of 133 x 86 x 70 mm (5.24 x 3.39 x 2.76″) and weighs 461 g (1.02 lb / 16.26 oz) (including batteries).
Below you can see the front-view size comparison of the Canon R100 and the Canon R8. Canon R100 is 17mm narrower and 1mm thinner than Canon R100 but they have the same height of 86mm.
Here is the back view size comparison of the Canon R100 and Canon R8.
Now lets look at the top view comparison of Canon R100 and Canon R8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon R100 is significantly lighter (105g ) than the Canon R8 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 also have to take into account the lenses that you will be using with these bodies. Since Canon R8 has a Full frame sensor and Canon R100 has a smaller APS-C sensor, Canon R100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon R8 lenses.
Weather Sealing
Thanks to the weather-sealed body of the R8, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the R100.
LCD Screen Size and Features
Canon R100 and Canon R8's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon R8 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. Canon R100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to R8.
