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 Nikon Z5 and Sony A6100 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 A6100 has external dimensions of 120 x 67 x 59 mm (4.72 x 2.64 x 2.32″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front view size comparison of Nikon Z5 and Sony A6100. Sony A6100 is clearly the smaller of the two cameras. Its body is 14mm narrower, 34mm shorter and 11mm thinner than Nikon Z5.
Here is the back view size comparison of Nikon Z5 and Sony A6100.
Now lets look at the top view comparison of Nikon Z5 and Sony A6100.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A6100 is significantly lighter (279g ) 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 have to also take into account the lenses that you will be using with these bodies. Since Nikon Z5 has a Full frame sensor and Sony A6100 has a smaller APS-C sensor, Sony A6100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon Z5 lenses.
With its weather sealed body, we believe that Z5 has a big advantage over A6100 which doesn't provide any kind of environmental sealing.
