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 RZ18 and Casio EX-10 side-by-side from the front, back and top in their relative dimensions. Pentax RZ18 has external dimensions of 97 x 61 x 33 mm (3.82 x 2.4 x 1.3″) and weighs 178 g (0.39 lb / 6.28 oz) (including batteries). Casio EX-10 has external dimensions of 120 x 68 x 49 mm (4.72 x 2.67 x 1.91″) and weighs 384 g (0.85 lb / 13.55 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax RZ18 and the Casio EX-10. Pentax RZ18 is clearly the smaller of the two cameras. Its body is 23mm narrower, 7mm shorter and 16mm thinner than Casio EX-10.
Here is the back view size comparison of the Pentax RZ18 and Casio EX-10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax RZ18 is significantly lighter (206g ) than the Casio EX-10 which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the RZ18 has a big advantage over the EX-10 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Casio EX-10's 3.50" LCD screen is slightly larger than Pentax RZ18's 3" screen.
In addition to the size advantage, Casio EX-10 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 RZ18 has a fixed type screen which provides less flexibility in shooting positions compared to EX-10.
