is this normal?

[ognjean]

just need some info, im using a 5d, with the sigma 8mm circular fish eye.
stitcher claims on being able to create a spherical file with just 2 pictures from this lens.
up till now i haven't been able to pull it off. now im trying to get it done with 6 shots and a zenit shot. even now i still get black rims on the image and ghosting around static objects.
tryed to calibrify the lens in stitcher but still keep on getting the same effects.also im pretty shure that the i found the nodal point and set it up on the tripod.????
anyone know what else i could try to get this fixed?

I've heard of a few photographers being able to get a good alignment and stitch from a 2 shots taken with a Sigma 8mm on a frull frame sensor. One sent me a pair of shots and I gor pretty good results using iPIX Interactive Studio but I could still see the seam. There just isn't that much overlap
On the other hand, 6 shots plus a zenith is massive overkill and the 300% overlap may be causing the problems like Ghosting
What are you using for a Panoramic Tripod Head?
What should work best with the Sigma 8mm and your 5D is 3 shots around
