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 D810 and Pentax K-1 II side-by-side from the front, back and top in their relative dimensions.
Below you can see the front view size comparison of Nikon D810 and Pentax K-1 II. Pentax K-1 II is 9mm narrower and 13mm shorter than Nikon D810 but it is also 4mm thicker.
Here is the back view size comparison of Nikon D810 and Pentax K-1 II.
Now lets look at the top view comparison of Nikon D810 and Pentax K-1 II.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon D810 is 30g lighter than the Pentax K-1 II but we don't think this will make a significant difference.
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 D810 and Pentax K-1 II have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

Weather Sealing
Both D810 and K-1 Mark II have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Nikon D810 and Pentax K-1 II's LCD screens has the same diagonal size of 3.2".
Both Nikon D810 and Pentax K-1 II have 36.0 MP resolution sensors but Nikon D810's sensor is Full frame (35.9 x 24 mm ) and Pentax K-1 II's sensor is Full frame (35.9 x 24 mm ).
Since Pentax K-1 II's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon D810.
Another similarity between these two cameras is that both Pentax K-1 II and Nikon D810 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.
Below you can see the D810 and K-1 Mark II sensor size comparison.
Nikon D810 and Pentax K-1 II have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
