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 T6s and Nikon D780 side-by-side from the front, back and top in their relative dimensions. Canon T6s has external dimensions of 132 x 101 x 78 mm (5.2 x 3.98 x 3.07″) and weighs 565 g (1.25 lb / 19.93 oz) (including batteries). Nikon D780 has external dimensions of 144 x 116 x 76 mm (5.67 x 4.57 x 2.99″) and weighs 840 g (1.85 lb / 29.63 oz) (including batteries).
Below you can see the front view size comparison of Canon T6s and Nikon D780. Canon T6s is 12mm narrower and 15mm shorter than Nikon D780 but it is also 2mm thicker.
Here is the back view size comparison of Canon T6s and Nikon D780.
Now lets look at the top view comparison of Canon T6s and Nikon D780.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon T6s is significantly lighter (275g ) than the Nikon D780 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 Nikon D780 has a Full frame sensor and Canon T6s has a smaller APS-C sensor, Canon T6s's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D780 lenses.
Thanks to the weather sealed body of D780, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to T6s.
