Hi
I've been searching the web and found a lot of resources on finding the
no-parallax point of a camera/lens and on pano heads and weights on
strings to help rotate the camera around this point. One question I
didn't find an answer to, though: If you're using a zoom lens, does
zooming move the no-parallax point? In other words, if I were to build a
fixed position pano head, would it lock me into using one particular
zoom level, e.g. 18 mm?
Yes.
But.
Since most people would ant the widest possible
lens, you're very likely to be "locked" at the
widest end of your zoom lens, so a fixed pano head
matched to this will (in practice) be fine.
Further, even if you were to be using your zoom at a longer
setting, you're likely to be further from your subject,
and thus the parallax error will (probably...) be
acceptable.
