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 Canon SL2 and Sony A68 side-by-side from the front, back and top in their relative dimensions. Canon SL2 has external dimensions of 122 x 93 x 70 mm (4.8 x 3.66 x 2.76″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries). Sony A68 has external dimensions of 143 x 104 x 81 mm (5.63 x 4.09 x 3.19″) and weighs 610 g (1.34 lb / 21.52 oz) (including batteries).
Below you can see the front view size comparison of Canon SL2 and Sony A68. Canon SL2 is clearly the smaller of the two cameras. Its body is 21mm narrower, 11mm shorter and 11mm thinner than Sony A68.
Here is the back view size comparison of Canon SL2 and Sony A68.
Now lets look at the top view comparison of Canon SL2 and Sony A68.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SL2 is significantly lighter (157g ) than the Sony A68 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 both Canon SL2 and Sony A68 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Unfortunately neither Canon EOS Rebel SL2 nor Sony SLT-A68 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top DSLR Cameras with Weather Sealing
