Hi all. I have my Canon 60D mounted to my new NN3 MKII with an Opteka Fisheye lens attached. Yesterday, I took the time to find the Nodal Point (its located at 9.2 on the upper rail).

I can get most of the shots no problem except for straight up Zenith shot. The max I can rotate the rig upwards is 55 Degrees, as the back of the camera collides with the base rotator. I am guessing that this is more than enough coverage with my fisheye attached to capture the Zenith, but when my 18-200 lens attached it hits the base as well. Does this mean my 18-200 lens will not be able to get the full 360 pano?

Thanks for the help.
