LCD Screen Size and Features
Panasonic ZS35's 3.00" LCD screen is slightly larger than Sony W570's 2.7" screen.
In addition to the size advantage, Panasonic ZS35 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, Sony W570 has a fixed type screen which provides less flexibility in shooting positions compared to ZS35.
