A number of good remarks from several people. I'm very new at the stitched
panoramics. Used a Bogen 3414 to index the rotation and a Cullman slide
plate on top of that for positioning the camera. Used PhotoVista for
stitching . . . and having tried a couple of others must agree that it is
among the simplest and best. A bit of fiddling around with it discovered
letting PhotoVista sort out what *exact* focal length to use seems to work
much better on most of them.
I will have to experiment more with the camera position . . . it is
rotating on the lens axis but not terribly certain if I got the rear node
position correctly yet. It seems to pass the "lamppost" parallax test but
is worth checking again and trying a round of vertical format instead of
horizontal. A couple also had some *very* near objects in the foreground
which probably amplify lens positioning error and any aberration.
I looked for rear node position data for the 28/3.5 on the data sheet that
came with the lens (bought new many years ago . . . and the lens hood is in
the top of the lens case). A diagram of the lens elements and outer
dimensions is on the sheet, but nothing about node locations. :-( I'm not
a lens expert but it looks as if there is a "reverse tele" at the back
which would make sense on a short focal length lens for an SLR (keeps the
lens rear far enough from the film plane to prevent a mirror from banging
into it). Anyone seen any node position data on the Zuiko's anywhere?
