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 Olympus XZ-2 iHS and Pentax E70 side-by-side from the front, back and top in their relative dimensions. 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). Pentax E70 has external dimensions of 94 x 61 x 26 mm (3.7 x 2.4 x 1.02″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus XZ-2 iHS and the Pentax E70. Pentax E70 is clearly the smaller of the two cameras. Its body is 19mm narrower, 4mm shorter and 22mm 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.
Pentax E70 is significantly lighter (171g ) than the Olympus XZ-2 iHS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus XZ-2 iHS nor Pentax Optio E70 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Olympus XZ-2 iHS's 3.00" LCD screen is slightly larger than Pentax E70's 2.4" 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, Pentax E70 has a fixed type screen which provides less flexibility in shooting positions compared to XZ-2 iHS.
