LCD Screen Size and Features
Nikon S9900 and Canon G15's LCD screens has the same diagonal size of 3".
On the other hand, Nikon S9900 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. Canon G15's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S9900.
