There is another possibility: if the user is too close
to the subject with the zomm at maximum tele position,
the Sony camcorder cannot focus - focus range varies
from the front surface of the lens at "wide", to maybe
4' minimum at tele zoom position. BTW, it is fairly normal
(or at least common) in Sony camcorders for the focus
to shift a bit within the last bit of tele range, so it is
unwise to focus at full (optical) tele in manual, then
zoom back. AF covers this, and AF is generally good enough
in the newer Sony camcorders to be used most of the time.
