Hi,
I recently purchased the Canon Powershot G9.
I would like to get into the realm of taking full spherical panoramic images.

What hardware would I need for this?
I know I need a fisheye converter, which one would you recommend? Would the VR head it be compatible with this camera?
What other hardware would I need to attach the camera to the VR head?
Would the NN3 work with this camera+fisheye converter ? or would I need the NN5?

What special features would I need in the tripod?

Thank you for your help.

Guy.
