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 Samsung SL30 and Olympus XZ-2 iHS side-by-side from the front, back and top in their relative dimensions. Samsung SL30 has external dimensions of 94 x 61 x 23 mm (3.7 x 2.4 x 0.91″) and weighs 140 g (0.31 lb / 4.94 oz) (including batteries). Olympus XZ-2 iHS has external dimensions of 113 x 65 x 48 mm (4.45 x 2.56 x 1.89″) and weighs 346 g (0.76 lb / 12.20 oz) (including batteries).
Below you can see the front view size comparison of Samsung SL30 and Olympus XZ-2 iHS. Samsung SL30 is clearly the smaller of the two cameras. Its body is 19mm narrower, 4mm shorter and 25mm thinner than Olympus XZ-2 iHS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung SL30 is significantly lighter (206g ) than the Olympus XZ-2 iHS which may become a big advantage especially on long walking trips.
Unfortunately neither Samsung SL30 (ES15) nor Olympus XZ-2 iHS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Olympus XZ-2 iHS's 3" LCD screen is slightly larger than Samsung SL30's 2.5" screen.
In addition to the size advantage, Olympus XZ-2 iHS LCD screen also has a Tilting feature
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Samsung SL30 has a fixed type screen which provides less flexibility in shooting positions compared to XZ-2 iHS.
