Richard, The shutter acts in the same manner without the strobe. When in the X position, the shutter remains open when depressing the shutter release. It works fine in the M position. It appears that I may have an issue, which is disappointing. I was hoping to use this camera on the cruise I'm going on the first of next month. Roger, I may have miss stated my model. All I am doing is connecting a sync cable between my flash and the camera. I re-verified my serial number and it points to a Automat Rolleiflex Model 4, Rolleiflex MX (type 1), or a Rolleiflex 3,5 A depending on the source you reference.
