I also use a ballhead that flips, so the Nodal Ninja without the pano head itself would be an option.
The Nodal Ninja is the pano head. It would need to sit on something that would provide it with a level base - either a 1) leveling base 2) ball head; or 3) whatever.
Quote: They are rather non-specific about what fits it; I saw info to the effect that the max is 10.7cm from tripod screw to 45 degree no parallax point. Are you saying all those lenses work with 360 with no parallax issues?
Now you are getting into the physical sizing of the pano head itself. For perfect stitching especially with views that would offer the opportunity for parallax, you are going to want to have sufficient room on the arms (especially the arm the camera body attaches to) to be adjustable - so as to accommodate the physical length of the lens that you are using.
To be perfectly honest, I very rarely do 360 panos. I usually do any where from 3 to about 9 frames - primarily 180's with some extra for cropping on either end. All the lenses fit well. I rarely take the time to setup everything exactly, because it really rarely matters (in my shooting). What I mean by this, is checking the nodal points placement above the central rotational axis - checking the arm's setting so that it's perfectly set up for the individual lens length, etc. The main reason why I use the pano head (NN3) is to maintain nice straight lines (fence lines, etc.) that run across the stitched image at an angle. If I shoot off of just a ballhead, with the camera body on top of the rotational axis, that tends to induce some curvature in some instances, since the nodal point is out in front of the entire assembly.
Here is an example of a fence line. There is enough detail in the final full size image to see the barb wire fence running in the foreground and there are another 2 or 3 frames off to the left that show it more clearly - but it's nice and straight. It's 9 frames wide off the NN. I used the 8-16 (I don't remember if I was at 8 or 16mm here - I went very wide for the vertical height in order to capture the clouds with sufficient sky for framing.
There was really only one shot that I have ever really had any problems with parallax and that was just off the ballhead. A small twig of a tree in the very immediate foreground, that I did not even consider - turned out to be a problem. Dumped it in post processing when it would not stitch, lesson learned. Now having said that, it is surprising how close things can be and not have any parallax problems. Here is stitch that was taken in total absolute darkness. Plopped the tripod down, and just shot off the ballhead, leveled with the levels in liveview, guessed on the amount of rotation for each frame, so there was lot's of overlap. 11 frames with the 18-35.
The person you really want to hear from is panoguy. If he doesn't show up here on this thread - PM him, as he does a lot of 360's. You problems using either a fisheye or a very wide where you are going to wrap the stitches completely around are going to be different. You are somewhat going for the minimal amount of overlap, as I tend to take a fair amount of overlap.
