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 Sony A65 and Pentax KP side-by-side from the front, back and top in their relative dimensions. 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). 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).
Below you can see the front-view size comparison of the Sony A65 and the Pentax KP.
Here is the back view size comparison of the Sony A65 and Pentax KP.
Now lets look at the top view comparison of Sony A65 and Pentax KP.
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 Sony A65 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
Thanks to the weather-sealed body of the KP, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the A65.
LCD Screen Size and Features
Sony A65 and Pentax KP'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.
