At 3 inches, the Samsung PL70 has a quite large display diagonal compared to most of the other digital cameras of this age and type. The smallest display diagonal of cameras that were released more than two years ago is 1", the largest is 3.5", and the average display diagonal is 2.6".
We compared all the other 3" screen digital cameras to this camera and we think because of their better review scores, the 500 HS, and the S110 both from Canon or the Nikon D3S are also worth considering.
If this camera display diagonal is not large enough for you then you might want to look at the Canon 1100 (3.2" and higher rated), or the Panasonic Lumix DMC-FX77 (3.5" and higher rated).
What does "display diagonal" mean?
