The display diagonals of cameras of a similar type and age to this camera range from 2" to 4.8". The Panasonic DMC-GX1 + G VARIO 14-42mm has a fairly large display diagonal (3 inches) compared to most of the other similar spec digital cameras that are a comparable age to this digital camera.
We think you might also be interested in some of the alternative 3" screen digital cameras currently available including because of their better review scores, the Sony SLT-A35Y + DT 18-55mm + DT 55-200mm, or the Samsung SAMSUNG DV300F.
If you are looking for a larger display diagonal then you might want to look at the Df (£2,039) (3.2" and higher rated), the D4 (£4,225) (3.2" and higher rated), or the D4S (£3,379.99) (3.2" and higher rated) all from Nikon.
