Wondering if anyone has a manual for the Zeiss Hologon camera and can check for instructions on using the T setting. Releasing the shutter via the shutter button opens the shutter in T setting but pressing it does not close it. It can be closed by either re-cocking the shutter via the film advance lever or by turning the shutter speed dial but I'm not sure which one is correct per Zeiss and do not want to use the wrong method in case it causes some kind of undue wear in the camera. If anyone can clarify that would be appreciated.
