You have to find your LRS only once. Then you have to check URS for the rest of the settings with other lenses.
Managed to get a tel number of your UK Post today I could call from NL. I gave them the right Post-code. So you should get the new screw the next days. It is already at your post office. Sorry for delay.
I managed to get a D800 and went for the settings of fisheye and prime lenses.
I'll set them to another thread. Mine are slightely different from yours for 14-24 @ zoom 14. Have a look.
Hi Heinz.......funny you should say that about the 14-24mm....I re-tested (before you put your results up) and came to the figure of 157.5..so not too far away. After testing my newly acquired 16mm, I got to the figure of 101mm. My Lower Rail is on the Nadir adapter the other way round from yours and is at 135mm, although this is tested by me pointing the camera straight down and aligning with the mark on the clamp, and then looking in Photoshop at the result......so I don't know if this is the correct way to do it.
Would like to know what setting you get to on the Lower Rail with it 'turned' the other way round on the adapter.
I replied in the other thread about the screw........thanks, received it today.
Thanks for your (and everyones) continued help.
Settings are critical because of two different ways to mount the vertical rail.
You can realized, that the vertical rail has slightly different position on the lower rail. Mounted without Nadir Adapter, flat side showing to end of rail and moved to the end ends up in a different rail position compared to the vertical rail mounted to Nadir Adapter / Extender with flat side to show to the bubble.
The Upper Rotator is mounted to different sides of the vertical rail as well.
