LCD Screen Size and Features
Casio EX-100's 3.50" LCD screen is slightly larger than Olympus SZ-11'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, Olympus SZ-11 has a fixed type screen which provides less flexibility in shooting positions compared to EX-100.
