I just got my Nodal Ninja 3 MKII w/Rotator R-D12 in the mail today. I'm trying to set it up right now with my Canon 5D Mark II and EF 16-35mm 2.8 L II Lens and I'm not sure on how to set the upper rail properly. I looked in the recommended settings for the 5D and my Lens and it says to set it at 119mm. The only problem is the with the camera mounting plate on it can't reach that far back on the rail. Does anyone have a work around for this or should I just upgrade to the NN5?
