LCD Screen Size and Features
Casio EX-100's 3.5" LCD screen is slightly larger than Panasonic FH27'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, Panasonic FH27 has a fixed type screen which provides less flexibility in shooting positions compared to EX-100.
