LCD Screen Size and Features
Olympus Tough-3000's 2.7" LCD screen is slightly larger than Canon SX20 IS's 2.5" screen.
On the other hand, Canon SX20 IS sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Olympus Tough-3000 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX20 IS.
