But what does that mean?
"Far sharper" can simply be a setting in the JPEG engine. Are you getting any additional real detail? Think carefully before you answer, this is a difficult question to accurately ascertain. Look up the concepts of accutance and contrast.

I think you misunderstood me. What I mean is the camera quality of the P4 is all I care about. I don't need avoidance, or battery life or anything else. If the camera is a big improvement I will buy one, if not I won't. Not sure why you're throwing such big words at me.
