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 D500 and Pentax KP side-by-side from the front, back and top in their relative dimensions. Nikon D500 has external dimensions of 147 x 115 x 81 mm (5.79 x 4.53 x 3.19″) and weighs 860 g (1.90 lb / 30.34 oz) (including batteries). Pentax KP has external dimensions of 132 x 101 x 76 mm (5.2 x 3.98 x 2.99″) and weighs 703 g (1.55 lb / 24.80 oz) (including batteries).
Below you can see the front view size comparison of Nikon D500 and Pentax KP. Pentax KP is clearly the smaller of the two cameras. Its body is 15mm narrower, 14mm shorter and 5mm thinner than Nikon D500.
Here is the back view size comparison of Nikon D500 and Pentax KP.
Now lets look at the top view comparison of Nikon D500 and Pentax KP.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax KP is significantly lighter (157g ) than the Nikon D500 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 both Nikon D500 and Pentax KP have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Both D500 and KP have weather sealings in their body, making them resistant to water and dust.
