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 II and Canon 6D MII 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 II and Canon 6D MII. Pentax K-3 II is 13mm narrower and 11mm shorter than Canon 6D MII but it is also 2mm thicker.
Here is the back view size comparison of Pentax K-3 II and Canon 6D MII.
Now lets look at the top view comparison of Pentax K-3 II and Canon 6D MII.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon 6D MII is 35g lighter than the Pentax K-3 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 Canon 6D MII has a Full frame sensor and Pentax K-3 II has a smaller APS-C sensor, Pentax K-3 II's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 6D MII lenses.

Weather Sealing
Both K-3 II and 6D MII have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Pentax K-3 II's 3.2" LCD screen is slightly larger than Canon 6D MII's 3" screen.
On the other hand, Canon 6D MII 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, Pentax K-3 II has a fixed type screen which provides almost no flexibility in shooting positions compared to 6D MII.
Pentax K-3 II has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Prime III processor. On the other hand, Canon 6D MII has a 26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features DIGIC 7 processor.
Another difference between these two cameras is that Pentax K-3 II'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 II and 6D MII sensor size comparison.
As seen above, Canon 6D MII has a 2.4x Larger sensor area than Pentax K-3 II. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Pentax K-3 II and Canon 6D MII sensors have been tested by DxO and the results show that 6D MII has a better overall score of 85, 5 points higher compared to K-3 II's score of 80.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Canon 6D MII has an advantage over Pentax K-3 II There are 249 lenses for Canon 6D MII's Canon EF mount, on the other hand there are only 151 lenses for Pentax K-3 II's Pentax KAF2 lens mount.
Another important factor is the availability of image stabilization. Both Pentax K-3 II and Canon 6D MII has Sensor based Image stabilization which means that all the lenses will be stabilized in these bodies.
