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 KP and Sony A77 II side-by-side from the front, back and top in their relative dimensions. 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). Sony A77 II has external dimensions of 143 x 104 x 81 mm (5.63 x 4.09 x 3.19″) and weighs 647 g (1.43 lb / 22.82 oz) (including batteries).

Here is the back view size comparison of Pentax KP and Sony A77 II.
Now lets look at the top view comparison of Pentax KP and Sony A77 II.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A77 II is 56g lighter than the Pentax KP 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 KP and Sony A77 II have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Both KP and A77 II have weather sealings in their body, making them resistant to water and dust.
