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 HX350 and Pentax K-5 II side-by-side from the front, back and top in their relative dimensions. Sony HX350 has external dimensions of 130 x 93 x 103 mm (5.12 x 3.66 x 4.06″) and weighs 652 g (1.44 lb / 23.00 oz) (including batteries). Pentax K-5 II has external dimensions of 131 x 97 x 73 mm (5.16 x 3.82 x 2.87″) and weighs 760 g (1.68 lb / 26.81 oz) (including batteries).
Below you can see the front-view size comparison of the Sony HX350 and the Pentax K-5 II. Sony HX350 is 1mm narrower and 4mm shorter than Pentax K-5 II but it is also 30mm thicker. As you can tell, actually this is not a fair size comparison since Sony HX350 has a built-in lens but Pentax K-5 II doesn't. Once you put a lens on K-5 II, its thickness will increase significantly.
Here is the back view size comparison of the Sony HX350 and Pentax K-5 II.
Now lets look at the top view comparison of Sony HX350 and Pentax K-5 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony HX350 is significantly lighter (108g ) than the Pentax K-5 II which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on K-5 II, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the K-5 II, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the HX350.
LCD Screen Size and Features
Sony HX350 and Pentax K-5 II's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony HX350 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Pentax K-5 II has a fixed type screen which provides less flexibility in shooting positions compared to HX350.
