Pardon my ignorance, but am i right in thinking that a camera with a 3 X
Optical Zoom having 5MPixels, is about the same as a camera having a 6 X
Optical Zoom with 2.5MPixels (i know you don't often get 2.5MP, but just
theoretically).

This weekend i was at the Sunderland Airshow, i have a Fuji Finepix
2800Zoom
(2.0MP, 6X Optical), i got reasonable pictures, and looking at the picture
on the PC monitor (and no zooming in/out of picture) the plane looks to be
about 7cm on screen. Now, what i am trying to find out is, forgetting
picture QUALITY, would i have got similar results with a camera with only
a
3X optical zoom, but having 4 or 5MP ? (i.e. without any zooming of the
picture on screen, would the plane still look to be 7cm ?.

Hope someone knows what i'm going on about !

Cheers
Andy
