Hi Carlos,
very nice panoramas but I wasn't mentioning the Opteka (don't know about
that lens). Also Emaad asked about the Samyang (see the subject).
And if I compare these two pages...
http://wiki.panotools.org/Stereographic_Projection
http://wiki.panotools.org/Fisheye_Projection
...there is some difference as I was earlier trying to point out with
the flickr link to one image from my 8mm f2.8 fisheye Nikkor. That one
certainly uses "circular fisheye".
Sure you can correct most of what you "cause" with a different
projection type with some overlap and proper optimization but still I
would set my input images to be stereographic if I was working with the
Samyang 8 mm.
Can you post one example shot from each of your indeed interesting
lenses (uncropped), so I can compare that side by side with my 8mm
Nikkor shot?

I have tested here with a project where I used before the lens as
"circular fish-eye". The result is about the same. The optimizations to
achieve the result have also been the same, so I really think it doesn't
make much difference and both will do well.

Well, up to now I have only used fish-eye as lens set and I have
already done plenty of indoor panoramas - they are in my blog. I
usually use the Opteka 6.5mm or a Sigma 10-20mm at 10mm. All made
with Opteka have used this setup, like the two last pictures in this
tour:
