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 A6600 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 A6600 has external dimensions of 120 x 67 x 69 mm (4.72 x 2.64 x 2.72″) and weighs 503 g (1.11 lb / 17.74 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon Z5 and the Sony A6600. Sony A6600 is clearly the smaller of the two cameras. Its body is 14mm narrower, 34mm shorter and 1mm thinner than Nikon Z5.
Here is the back view size comparison of the Nikon Z5 and Sony A6600.
Now lets look at the top view comparison of Nikon Z5 and Sony A6600.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6600 is significantly lighter (172g ) than the Nikon Z5 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 Z5 has a Full frame sensor and Sony A6600 has a smaller APS-C sensor, Sony A6600's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon Z5 lenses.
