is anyone here using the rollei X-Act or X-Act2? i am looking to add to my existing 6008 outfit and the X-act is on my list...i am mostly interested in shooting with my 6000 series lenses and my P20 back....i understand that i need the camera body and the shutter control and probably the pan shot....do i need a special adapter for the 6000 series lenses? do i need an adapter to put the P20 or 645mag on the camera? i know that the P20 and 645 mag would be useable on the pan shot, but i am wondering if there is a way to use them without the pan shot as well? any input welcome..thanks
