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 D5200 and Nikon D6 side-by-side from the front, back and top in their relative dimensions. Nikon D5200 has external dimensions of 129 x 98 x 78 mm (5.08 x 3.86 x 3.07″) and weighs 555 g (1.22 lb / 19.58 oz) (including batteries). Nikon D6 has external dimensions of 160 x 163 x 92 mm (6.3 x 6.42 x 3.62″) and weighs 1270 g (2.80 lb / 44.80 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D5200 and the Nikon D6. Nikon D5200 is clearly the smaller of the two cameras. Its body is 31mm narrower, 65mm shorter and 14mm thinner than Nikon D6.
Here is the back view size comparison of the Nikon D5200 and Nikon D6.
Now lets look at the top view comparison of Nikon D5200 and Nikon D6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon D5200 is significantly lighter (715g ) than the Nikon D6 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 D6 has a Full frame sensor and Nikon D5200 has a smaller APS-C sensor, Nikon D5200's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D6 lenses.
Weather Sealing
Thanks to the weather-sealed body of the D6, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the D5200.
LCD Screen Size and Features
Nikon D6's 3.20" LCD screen is slightly larger than Nikon D5200's 3 screen.
On the other hand, Nikon D5200 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Nikon D6 has a fixed type screen which provides almost no flexibility in shooting positions compared to D5200.
