I've been happily using my CFV on my 503 CW and SWC/M for some time now. I'm hoping to acquire a 200 series camera, 201F most likely, to use with the CFV. Based on what I've found on the net it is possible to use the CFV on an unmodified 200 or even 2000 series camera up to its fastest shutter speed if I use a pricey Kapture HA-001 cable ($300). This looks like a cable release that also has a connector from the camera flash sync to the CFV back. Do I really need the specific Kapture cable or can I use a separate cable release and the sync to CFV connector?
