Camcorder zooms aren't that obvious. What still photgraphers call a "zoom"
is called an "optical zoom" in camcorder ads. Digital zoom is cutting
pixels out of the center and interpolating (or sometimes just replicating)
them to full size. One camcorder I saw advertised a 72X "digital zoom"!
Talk about worthless.
Many camcorders mix "digital" and "optical" with the digital cutting in
when the real zoom stops.
A lot of digital cameras have "digital zooms", too. OMs have the
equivalent: Cut a 1mm by 1.5mm bit from the center of
a negative, enlarge it to 8x10, and you have a 24X "enlarger zoom".
