After a couple of trials, it was pointed out to me else where that the settings for the 40D+10-22 needs to be adjusted. I have a NN3 MKII head and I used the settings recommended in the camera settings.
Anyways, I tried to recalculate the numbers manually and came up with this:
Lower Rail 'A' = 43 mm
Upper Rail 'B' = 104.5 mm
If I could push the camera backward a little more I would have because the settings in B is the closest thing to correct but not exactly.
Can someone confirm the numbers?
