You mean you are using optical -zoom- not digital zoom. Every digital
camera is also "optical" in that they all use lenses.

It still appears pixellated. I see groups of 3 pixels on a side that
appear to be very much the same in brightness.

DPI is meaningless when it comes to a camera. Can you tell me what the
CCD size is in pixels?
