Patrick,

The current Pro SD lenses will accept a standard cable release which closes the shutter, when set to "T". Earlier lenses have a "T" setting (but not "B") and the shutter is closed by moving the speed dial off the "T" setting or a by slight movement of the winding lever

Just to confirm, do all the RB67 models have both a B and a T setting? What is confusing me is that some people claim that when they are utilising the B function, they have to first open the shutter to start the exposure and then operate the shutter again to end the exposure, risking vibration in the final photograph. To me, this seems like a T setting as opposed to a B setting. Is it indeed possible with an RB67 to keep the shutter open with continual pressure of the cable release and then close the shutter by releasing the cable release, just like with a regular B setting?
