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 6D MII and Nikon D780 side-by-side from the front, back and top in their relative dimensions. Canon 6D MII has external dimensions of 144 x 111 x 75 mm (5.67 x 4.37 x 2.95″) and weighs 765 g (1.69 lb / 26.98 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon 6D MII is 75g lighter than the Nikon D780 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 have to also take into account the lenses that you will be using with these bodies. Since both Canon 6D MII and Nikon D780 have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Both 6D MII and D780 have weather sealings in their body, making them resistant to water and dust.
