The Samsung 30F has a quite large display diagonal (3 inches) compared to most of the other similar spec digital cameras that came out around the same time as this camera. Across all the similar spec digital cameras that are a comparable age to this digital camera the display diagonals range from 2" to 4.8", and the average display diagonal is 2.9".
It may also be worth also looking at one of the alternative 3" screen cameras currently available including the Sony SLT-A35Y + DT 18-55mm + DT 55-200mm, or the Samsung SAMSUNG DV300F which both of have better reviews.
If you would prefer a digital camera with 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.
