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 T7 and Nikon D780 side-by-side from the front, back and top in their relative dimensions. Canon T7 has external dimensions of 129 x 101 x 78 mm (5.08 x 3.98 x 3.07″) and weighs 475 g (1.05 lb / 16.76 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 the Canon T7 and the Nikon D780. Canon T7 is 15mm narrower and 15mm shorter than Nikon D780 but it is also 2mm thicker.
Here is the back view size comparison of the Canon T7 and Nikon D780.
Now lets look at the top view comparison of Canon T7 and Nikon D780.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon T7 is significantly lighter (365g ) 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 also have to take into account the lenses that you will be using with these bodies. Since Nikon D780 has a Full frame sensor and Canon T7 has a smaller APS-C sensor, Canon T7's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D780 lenses.
Weather Sealing
Thanks to the weather-sealed body of the D780, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the T7.
LCD Screen Size and Features
Nikon D780's 3.20" LCD screen is slightly larger than Canon T7's 3 screen.
In addition to the size advantage, Nikon D780 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Canon T7 has a fixed type screen which provides less flexibility in shooting positions compared to D780.
