LCD Screen Size and Features
Casio EX-100's 3.50" LCD screen is slightly larger than Canon G16'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, Canon G16 has a fixed type screen which provides less flexibility in shooting positions compared to EX-100.
