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 Nikon Z5 and Sony A9 II side-by-side from the front, back and top in their relative dimensions. Nikon Z5 has external dimensions of 134 x 101 x 70 mm (5.28 x 3.98 x 2.76″) and weighs 675 g (1.49 lb / 23.81 oz) (including batteries). Sony A9 II has external dimensions of 129 x 96 x 76 mm (5.08 x 3.78 x 2.99″) and weighs 678 g (1.49 lb / 23.92 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon Z5 and the Sony A9 II. Sony A9 II is 5mm narrower and 5mm shorter than Nikon Z5 but it is also 6mm thicker.
Here is the back view size comparison of the Nikon Z5 and Sony A9 II.
Now lets look at the top view comparison of Nikon Z5 and Sony A9 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon Z5 is 3g lighter than the Sony A9 II 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 also have to take into account the lenses that you will be using with these bodies. Since both Nikon Z5 and Sony A9 II have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

Both the Z5 and the A9 Mark II have weather sealings in their bodies, making them resistant to water and dust.
