I agree with Andrew the fullframe fisheyes wiill give you less problems.
Actually I thought you already worked with a fullframe for 35 mm film.
You are on Nikon so my advice is to look for the new 10.5 mm fullframe
NIKKOR fisheye.

It is specially made for Digital and gives you the same on your D1 as the
16mm on a fullframe digital or 35 mm film.
It should be out in a couple of months and the price seems to be just
slightly more than the Sigma 8mm. Probably around 1000 euro
I have seen an estimated price of #599
And it is 2.8 the SiGMA is 4.0
The resolution you have on the D1 is to small for the Sigma 8mm but with the
10.5 mm you can get a cubic sized 2600x5200 pix and I am sure the quality
will be better than I get with the Sigma 8 mm on D60. They are 3000x6000
If you want more resolution there are several Digitals for NIKKOR lenses
including the cheap D100
If I where to buy a digital today I wood choose it. You can always buy a
SIGMA 8mm for fast 4 shot panoramas. I just hope Canon gets the same idea
now.
And stitching is easier than with the 8 mm. You can probably convert
directly to rectilinear with Nikons own new Nikon Capture 4.0 software's
unique 'Fisheye-to-Rectilinear Image Transformation' capability.
Then stitch in any software for cylindrics including QTVRAS. Import
directly in Cubic Converter and ad the top and bottom with the
export/import functions.
I have by the way a question to Click here design. Importing Cylindric
images/movies seems to have a limit at 800x800 Cube faces.
You can choose larger but this seems to just interpolate the 800x800 faces
and not the original image. Am I doing something wrong ?.
Of course I just convert my images in Panotools to spheric instead but it
would be easier to be able to convert directly.
