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 Pentax K-3 and Pentax KP side-by-side from the front, back and top in their relative dimensions.
Below you can see the front view size comparison of Pentax K-3 and Pentax KP. Pentax K-3 is 1mm narrower and 1mm shorter than Pentax KP but it is also 1mm thicker.
Here is the back view size comparison of Pentax K-3 and Pentax KP.
Now lets look at the top view comparison of Pentax K-3 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 97g lighter than the Pentax K-3 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 Pentax K-3 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.

Weather Sealing
Both K-3 and KP have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Pentax K-3's 3.2" LCD screen is slightly larger than Pentax KP's 3" screen.
Both Pentax K-3 and Pentax KP have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another difference between these two cameras is that Pentax K-3's sensor lacks anti-alias (Low-Pass) filter. 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 K-3 and KP sensor size comparison.
Pentax K-3 and Pentax KP have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
In this section, we rank and compare Pentax K-3 and Pentax KP for five different photography types in order to make your decision process easier in case you are specifically interested in one or more of these areas.
