LCD Screen Size and Features
Casio EX-10's 3.5" LCD screen is slightly larger than Canon SX120 IS'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, Canon SX120 IS has a fixed type screen which provides less flexibility in shooting positions compared to EX-10.
