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 SL3 and Canon 80D side-by-side from the front, back and top in their relative dimensions. Canon SL3 has external dimensions of 122 x 93 x 70 mm (4.8 x 3.66 x 2.76″) and weighs 449 g (0.99 lb / 15.84 oz) (including batteries). Canon 80D has external dimensions of 139 x 105 x 79 mm (5.47 x 4.13 x 3.11″) and weighs 730 g (1.61 lb / 25.75 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SL3 and the Canon 80D. Canon SL3 is clearly the smaller of the two cameras. Its body is 17mm narrower, 12mm shorter and 9mm thinner than Canon 80D.
Here is the back view size comparison of the Canon SL3 and Canon 80D.
Now lets look at the top view comparison of Canon SL3 and Canon 80D.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SL3 is significantly lighter (281g ) than the Canon 80D 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 both Canon SL3 and Canon 80D have the same Canon EF/EF-S lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Thanks to the weather-sealed body of the 80D, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SL3.
LCD Screen Size and Features
Canon SL3 and Canon 80D's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
