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 Sony a3500 and Nikon Z5 side-by-side from the front, back and top in their relative dimensions. Sony a3500 has external dimensions of 128 x 91 x 85 mm (5.04 x 3.58 x 3.35″) and weighs 411 g (0.91 lb / 14.50 oz) (including batteries). 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).
Below you can see the front view size comparison of Sony a3500 and Nikon Z5. Sony a3500 is 6mm narrower and 10mm shorter than Nikon Z5 but it is also 15mm thicker.
Now lets look at the top view comparison of Sony a3500 and Nikon Z5.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony a3500 is significantly lighter (264g ) 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 a3500 has a smaller APS-C sensor, Sony a3500's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon Z5 lenses.
Thanks to the weather sealed body of Z5, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to a3500.
LCD Screen Size and Features
Nikon Z5's 3.2 LCD screen is slightly larger than Sony a3500's 3" screen.
In addition to the size advantage, Nikon Z5 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, Sony a3500 has a fixed type screen which provides less flexibility in shooting positions compared to Z5.
