Will,
yes - thank you for that link.

Well I remember looking at the very first pano on that page (a while back),
expanding to full screen
and thinking to myself - why so blurry? I realize now that it was probably
not
intended to be full screen (I think those panos are much SMALLER than the
maximum
quality of 6000 x 3000 panos with that setup).
The reason why I thought they were blurry is because I had the following
panos in mind
at Hans Nyberg site:
http://www.panoramas.dk/d60/
The setup is similar at Han's site: 6 MP camera (D60) with 8mm Sigma. But I
realize now that those panos
are 6000 x 3000 pixels, so when I have at full screen those panos are
reasonably sharp. Compare the
panos from Karl and Hans, they have different quality. I suppose they also
use a different HFOV
in QuickTime viewer.
A better guage of the Canon 10D + Sigma 8mm would be if Karl had created the
6000 x 3000 pixel version of
any one of his panos posted, at a lower compression. It does not seem that
he posted the maximum
quality output from his setup (I hope).
As you know, the Canon 10D is also ~ 6 MP. Of course, I suppose you could
also consider the
Canon EF 15mm fisheye for the same price as a Sigma 8mm (used with the 10D),
except you would
have to shoot 2 rows of 9 shots, and 1 or 2 shots at Zenith, 1 or 2 shots at
Nadir. More
work, but then you could get ~ 11,000 x 5500 pixel panos, downsampled to
whatever for razor sharp
stuff if you are not happy with the Sigma 8mm (alot more work, though).
Supposedly the 15mm EF
has very little light falloff, and is sharp out to the edges (when used with
a 10D sensor, or so I've read) - i
t has ~60 degrees and ~ 90 degrees on that size sensor.
I'm sure everyone here will correct all my rantings :-)
