yes the whole lens turns
but currently the TILT and SHIFT are 90 deg apart
what I want to do is SHIFT vertically and TILT vertically
when I use the tab they remain in hrz/vert config, just swap axes
hope I'm clear...
Try reading the instructions - there are two tabs and so the shift part of the lens can be rotated independently of the the tilt part of lens.
There is no need to disassemble the lens!!
