Joe - Thank you for your easy-to-understand explanation.  I have been so
confused about this and have tried to understand it.  In finally makes
sense.  It's about equal to what a digital zoom does on some of the cameras.
It essentially is zooming in on  the center of the image and is making that
part of the image and enlarging it so it will fill the whole frame (thus a
not-so sharp image).  The only thing making me want a removable lens DSLR is
that I felt I could get a 450 lens ( or thereabouts) out of my rather
inexpensive Tamron 70-300 zoom.  That sounded good, but to me sharpness and
clarity is more important.   Let me know if I am misinterpreting what you
said.
Thanks again.
