Canon 5d with Canon 15mm fisheye - Please help

Ok, so I'm a total newb when it comes to panorama photography so bare with me.
I am having issues with some panos, but others are turning out 100% perfect. I am using a Canon 5d camera, with Canon EF 15mm f/2.8 Fisheye Lens. I am also using a Kaidan Rotator Set pano head, with a kessler crane k-pod system tripod. I am using PTGui for stitching.
I am currently just doing test shots until i feel confident enough to start doing shots of my company's hotel resort. I need to be able to show my superiors that i have a standard to go by when i start shooting at the hotel.
I started off by doing 12 total shots, 6 shots up at 30 degrees, and 6 shots down at 30 degrees. I ran into problems when i moved into a small office, and ended up having to do 10 up at 30 degrees, and 10 down at 30 degrees.
Now that i have moved back out into the large area trying to shoot 10 up and 10 down, im having tons of issues.
When i shoot the top half of the room, i find the no-parallax-point and shoot the 360. i angle the camera down and find the no-parallax-point and shoot the 360 again. Is this the process im supposed to be taking? is it normal to having to find the no-parallax-point every time i angle up and down, or move from small to large room?
These 2 we taken with 2 rows of 6 shots, at 30 degrees up, 30 degrees down. I clone tooled the tripod out with photoshop.
This shot would not stitch together at all with 6 up and 6 down so after hours of messing with things I switched to 10 up at 30 degrees and 10 down at 30 degrees and it finally worked.
I just tried this 10 up and 10 down shot and its not even close.
Can anyone give me some feedback on if i am doing anything right, or what things i am doing wrong?
Sorry for the long thread, and thank you for reading.

The Canon 15mm FE is fullframe FE on the Canon 5D - it produces an image with 180 degrees FOV on the diagonal.
You need shoot only 6-around plus zenith and nadir.
If you have featureless images at the zenith as some of tescens above do - plain celings - then shoot one or more 'zenith' shots at less than +90 pitch - try +60-65 degress, so that you are more likely to get good links between 'zenith' and the main row of 6-around.
I shoot with a cropped sensor Nikon and the Nikkor 10.5mm fullframe FE lens - a system that is image-wise similar to yours.
I usually shoot 6-around at about -10 pitch and one or two up at about +60-65 pitch. This leaves just small 'hole' at the nadir no larger than the footprint of the rotator of my Nodal Ninja 5 pano head.
Give it a go - my image sets stitch very easily using Autopano Pro.
Just which type of Kaidan head do you have?
You should never need to set the NPP more than once for any lens/camera combo.

Really
Where did you get the information to shoot all these images. Unless you forgot a zero and you actually mean Canon 50D you are completely on the wrong track.
You only need to shoot 6 around + 1 zenith If you can set you head to shoot the 6 around at -10 degree you get the best coverage. Your combination is one of the best for very professional panoramas and the 6+1 stitches perfect always.
You can shoot the zenith image at 65-70 degrees if you have a zenith which has difficulties to find control point. at 65 degrees you still have the same coverage of the zenith as at 90 degrees but you get the horizont in the image where you can almost always find controlpoints.

Just 6 around at -15 or -10 and 1 or 2 at +60 are needed. The Kaiden is a way overpriced thing but it should work. Send it back and go for a NN5.. or keep the Kaidan and find the correct NPP for this lens/camera combo www.johnhpanos.com/tuts.htm is a very good starting point. So every shot more than 8 is quite useless. GoodLuck!

Hey guys, thanks for the advice i really appreciate it! I retried the last shot with 6 around at 15 degrees down, and then one zenith shot and it turned out great. I have yet to move back into the small office and seeing if i have any issues, so i will update you guys on that.
As far as the pano head goes, im pretty much stuck with this one. when we took on the project we had about 8 hours to come up with the equipment needed and put in the PO so im stuck with what i have now Same goes for software. we pretty much bought all the easypano software, panoweaver, tourweaver, etc...
@Hans I'm definately using a 5d camera.
One question about the nadir though. after i stitch i have a black hole. What process do i use to fill that in with the carpet/floor? or am i supposed to take a handheld nadir shot, and if so, how should i hold the camera?
Thanks a lot guys! I look forward to working out the kinks and showing u guy some cool resort/casino panos, hehe.

I have the exact same set-up and have just ordered a pano head.
Question: You shot 6 around at 10 degrees down and one nadir shot. Was the nadir shot straight up?
Thanks,
Dave

Could you explain why the 5D is not recommended for panoramas?

Hi fotomec, the 5D is very recommended for panoramas. No doubts about that.

Did you mean zenith when you said nadir?
If you in fact meant zenith - then with similar set up I usually shoot the 'zenith' at about +65 degrees rather than +90 (straight up) becaus if the zenith is relatively featureless (say clear sky or a relatively featureless ceilning) then shooting at +65 rather than +90 means you are more likely to get a good link between the 'zenith' and the main row, and you will still have full coverage of the zenith.

Andrew,
Yes, I meant zenith. Thank you - I will give this a try and see how it works out. I am about to shoot my first pano as my NN5 just arrived. I will post it and hopefully you guys can give me some feedback. One last question - should I use the camera set up recipe on the NN website for this camera and lens combo or am I better off determining the no paralax point using John Houghton's method posted on his website?
Thanks,
Dave

Use the settings on the website but check using the methods described in my tutorial. This doesn't take long and you can tweak the settings if necessary.
