For those ask on how to rotate the PC lens. It is quite simple
1)Open the 4 screw can be tight if you have a solder iron just heat the screw a bit to loosen up the lock-tite
2)Use an knife or scissor to cut the tape which make the ribbon shorter
3)Rotate and put the 4 screw back
for those who concern about the long wire will get caught in the gear that won\'t happen since it doesn\'t touch the gear when you put it back. Beside it is very slipper plastic which is really hard for the gear to grab it. Have fun. I will do the same thing with my nikon 24 PC-E and post pictures later. Here is a link someone else already did
