    You should mount the camera on the upper rail. Tilt the upper rail up by 5 deg, take 3 shots around.
    Try to do the calibration yourself. It takes just a few minutes.

    For the 4.5mm lens, use the camera in portrait orientation on the top rail of the NN5 and take 3 shots around. The pano head will intrude very slightly on the right, but will be of little consequence. If you want to try 2 back-to-back shots, then mount the camera in landscape orientation on the bottom rail.

    I haven't been very happy with the sigma 4.5mm. I need 6 shots for a full spherical and I loose a lot of resolution. I'm not sure how anyone is able to do one with just 2 or 3 shots.

    So now I'm looking at trying out the Sigma 8mm or the Nikon 10.5 f2.8 AF DX Fisheye. Does anyone know where I can get samples from the Nikon 10.5 to try out? Does anyone have any opinions on the two lenses?

    Thanks!

    when you say 6 shots, do you mean 4 shots around + one zenith and one nadir?
    On NN180, R1 or R10, you only need 3 shots around+ nadir.
    you can find some sample shots here

    Just a thought: the Sigma 8mm has a collar that the lens cap clips into. It is a common mistake for people to not to remove the collar (a push fit) from their new lens, in which case you get a much reduced angle of view. I imagine the 4.5mm lens has a similar collar, so could it be that you haven't removed it? That would account for you needing 6 shots around.

    Just thought I would let everyone know that I ended up going with the Nikon 10.5 f2.8 AF DX Fisheye lens and I couldn't be happier!

    Here is a link to a recent tour I finished using the lens and the NN5...

    Your panoramas are in need of levelling. In a equirectangular image, all the vertical features like sides of doors, walls, windows etc. should normally be exactly vertical - not leaning over to one side. If using PTGui, see http://www.johnhpanos.com/levtut.htm. Autopano Pro also has a levelling option.

    Hey John,

    I was wondering about the leveling thing. I'm using RealViz Stitcher Unlimited 5.6 on a mac. Do you know if there is a way to do it with that?

    Greg, I don't know if there is a specific levelling tool in Stitcher, but you can roll the image and shift it up and down to level it visually, as far as I can remember. At worst, you could download Hugin for free and import the equirectangular image for levelling using t1 control points as in PTGui.

    For fisheye lens, you need to mount in portrait mode. Sigma 4.5mm will required 3 shots.
