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 7D MII and Canon SL3 side-by-side from the front, back and top in their relative dimensions. Canon 7D MII has external dimensions of 149 x 112 x 78 mm (5.87 x 4.41 x 3.07″) and weighs 910 g (2.01 lb / 32.10 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Canon 7D MII and the Canon SL3. Canon SL3 is clearly the smaller of the two cameras. Its body is 27mm narrower, 19mm shorter and 8mm thinner than Canon 7D MII.
Here is the back view size comparison of the Canon 7D MII and Canon SL3.
Now lets look at the top view comparison of Canon 7D MII and Canon SL3.
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 (461g ) than the Canon 7D MII 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 7D MII and Canon SL3 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
With its weather-sealed body, we believe that the 7D MII has a big advantage over the SL3 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon 7D MII and Canon SL3's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon SL3 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 7D MII's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to SL3.
