I own a Nodal Ninja Ultimate M1 pano head with nadir adapter. I use it with a nikkor 14-24mm f/2.8 on a D800 with great results.
For the Google Trusted Photographer program (google business view for google places), the google software cannot stitch the pictures of a nikkor 14-24mm together. So i have to switch to a Sigma 8mm f/3.5 ex dg.
My question: Can i use the Ultimate M1 with the Sigma 8mm f/3.5 ex dg? Will parts of the Ultimate M1 show up in the pictures because of this extreme the 180° sigma fisheye lens?
I know the R10 is a better and easier choice for the sigma 8mm, but i do not want to buy another panohead unless the Ultimate M1 is hopeless to work with in combination with the sigma 8mm.
