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 Sony A6400 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). Sony A6400 has external dimensions of 120 x 67 x 60 mm (4.72 x 2.64 x 2.36″) and weighs 403 g (0.89 lb / 14.22 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SL3 and the Sony A6400. Sony A6400 is clearly the smaller of the two cameras. Its body is 2mm narrower, 26mm shorter and 10mm thinner than Canon SL3.
Here is the back view size comparison of the Canon SL3 and Sony A6400.
Now lets look at the top view comparison of Canon SL3 and Sony A6400.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6400 is 46g lighter than the Canon SL3 but we don't think this will make a significant difference.
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 Sony A6400 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Thanks to the weather-sealed body of the A6400, 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 Sony A6400's LCD screens have the same diagonal size of 3.00 inches.
Sony A6400 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Canon SL3 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
