Pardon my ignorance, but am i right in thinking that a camera with a 3 X

Optical Zoom with 2.5MPixels (i know you don't often get 2.5MP, but just
theoretically).

That depends on what you are planning to photo.

If it is something that fills the frame and where
you want to be able to make larger prints - no.

If it is song birds that fills just a small bit
of the actual frame, you can actually get away with
1.5 Mpixels at 6x zoom.

But - in the latter case - 20x zoom would be better.
