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 KP and Sony A65 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 A65 has external dimensions of 132 x 97 x 81 mm (5.2 x 3.82 x 3.19″) and weighs 622 g (1.37 lb / 21.94 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax KP and the Sony A65.
Here is the back view size comparison of the Pentax KP and Sony A65.
Now lets look at the top view comparison of Pentax KP and Sony A65.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A65 is 81g 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 also have to take into account the lenses that you will be using with these bodies. Since both Pentax KP and Sony A65 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
With its weather-sealed body, we believe that the KP has a big advantage over the A65 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax KP and Sony A65's LCD screens have the same diagonal size of 3.00 inches.
Pentax KP features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Sony A65 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
