LCD Screen Size and Features
Nikon P7100's 3.00" LCD screen is slightly larger than Canon A1100 IS's 2.5" screen.
In addition to the size advantage, Nikon P7100 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 A1100 IS has a fixed type screen which provides less flexibility in shooting positions compared to P7100.
