Anders,
With the SWC, I would set the camera to SWC and change the capture time to 1 sec. The reason is the film armature that pokes the magazine and in the case of the CFV the capture is longer than the 500 C series and starts the capture before the lens opens and exposes creating a half image. You will also get this if you slowly squeeze the camera trigger as the arm pokes out and starts the capture. If you increase the capture time, you will have less of an issue. Or you can put the sync cord in and shoot that way. -Al
Thank you for your good advice! I will try it out. I have used to shoot with the sync cord in, but it is a little loose. Maybe a service is needed.
