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 Pentax KF and Pentax K-70 side-by-side from the front, back and top in their relative dimensions. Pentax KF has external dimensions of 126 x 93 x 74 mm (4.94 x 3.66 x 2.91″) and weighs 684 g (1.50 lb / 24.12 oz) (including batteries). Pentax K-70 has external dimensions of 126 x 93 x 74 mm (4.94 x 3.66 x 2.91″) and weighs 688 g (1.52 lb / 24.27 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax KF and the Pentax K-70. In this case, we can see that Pentax KF and Pentax K-70 have the exact same height, width and thickness.
Here is the back view size comparison of the Pentax KF and Pentax K-70.
Now lets look at the top view comparison of Pentax KF and Pentax K-70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax KF is 4g lighter than the Pentax K-70 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 also have to take into account the lenses that you will be using with these bodies. Since both Pentax KF and Pentax K-70 have the same Pentax KAF2 lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Both the KF and the K-70 have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Pentax KF and Pentax K-70's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
