Got the D800 about two weeks ago - seems to live up to all the hype. Looking forward to using the in-camera HDR for with a panorama.
Settings I have come up for the D800 on the M1-L:
Lower rail setting: 13.55
For the Nikon 16mm Fisheye, using the short upper, MF-170, rail: 11.9
For the Nikon 70-300 using the long upper, MF-210, rail the setting for all mm from 70 to 300 is 15.8
Would greatly appreciate if someone is would double check
My vision is such that I'm not always sure of fine adjsutments.
