I have the 10-22 but am having trouble getting 360 degree
panos working properly (PTAssmbler v3) but I'm not trying to
do top and bottom as well. I've read others stating that they
can do a full sphere in 8-9: 6 for the horizontals, 2up and
1 down. So if you're not trying to do a sphere - just a 360 -
and you're on the nodal point so you may be able to work
with less overlap, then 6 is certainly possible. I've working
with 7 or 8 at the moment and having troubles (can anyone assist
in using PTa to do 360s from the 10-22?).
Cheers
Robert
PS. I'm using a 350D rather than 20D but that won't change
anything about the above...
