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 K-S2 and Olympus SH-2 side-by-side from the front, back and top in their relative dimensions. Pentax K-S2 has external dimensions of 123 x 91 x 73 mm (3.58 x 4.84 x 2.87″) and weighs 678 g (1.49 lb / 23.92 oz) (including batteries). Olympus SH-2 has external dimensions of 109 x 63 x 42 mm (4.29 x 2.48 x 1.65″) and weighs 271 g (0.60 lb / 9.56 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax K-S2 and the Olympus SH-2. Olympus SH-2 is clearly the smaller of the two cameras. Its body is 14mm narrower, 28mm shorter and 31mm thinner than Pentax K-S2. As you can tell, actually this is not a fair size comparison since Olympus SH-2 has a built-in lens but Pentax K-S2 doesn't. Once you put a lens on K-S2, its thickness will increase significantly.
Here is the back view size comparison of the Pentax K-S2 and Olympus SH-2.
Now lets look at the top view comparison of Pentax K-S2 and Olympus SH-2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SH-2 is significantly lighter (407g ) than the Pentax K-S2 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-S2, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the K-S2 has a big advantage over the SH-2 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax K-S2 and Olympus SH-2's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Pentax K-S2 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Olympus SH-2's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to K-S2.
