LCD Screen Size and Features
Casio EX-ZR1000's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7 screen.
In addition to the size advantage, Casio EX-ZR1000 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 ELPH 150 IS has a fixed type screen which provides less flexibility in shooting positions compared to EX-ZR1000.
