LCD Screen Size and Features
Olympus TG-1 iHS and Nikon P7800's LCD screens has the same diagonal size of 3".
On the other hand, Nikon P7800 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. Olympus TG-1 iHS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7800.
