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 600D and Canon 60Da side-by-side from the front, back and top in their relative dimensions. Canon 600D has external dimensions of 133 x 100 x 80 mm (5.24 x 3.94 x 3.15″) and weighs 570 g (1.26 lb / 20.11 oz) (including batteries). Canon 60Da has external dimensions of 145 x 106 x 79 mm (5.71 x 4.17 x 3.11″) and weighs 755 g (1.66 lb / 26.63 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 600D and the Canon 60Da. Canon 600D is 12mm narrower and 6mm shorter than Canon 60Da but it is also 1mm thicker.
Here is the back view size comparison of the Canon 600D and Canon 60Da.
Now lets look at the top view comparison of Canon 600D and Canon 60Da.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon 600D is significantly lighter (185g ) than the Canon 60Da 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 600D and Canon 60Da 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 60Da, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the 600D.
LCD Screen Size and Features
Canon 600D and Canon 60Da'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.
