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 (211g ) than the Casio EX-100 which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather sealed body, we believe that RZ18 has a big advantage over EX-100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Casio EX-100's 3.50" LCD screen is slightly larger than Pentax RZ18's 3" screen.
In addition to the size advantage, Casio EX-100 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-100.
