I have a question from a colleague who has recently purchased an NN3 to use with a Nikon outfit with an APS sensor and Nikon 16mm fisheye lens and who needs guidance on the number of shots to take to create a full spherical panorama.

I have used Frank's calculator at:
www.frankvanderpol.nl/fov_pan_calc.htm
and made my own calculations, but do not have a 16mm fisheye to test them with, so am asking for anyone who has used this combination if they would like to pass on their experiences please?

Unfortunately he is some 4000Km from me so I cannot just pop round and have a look.
