OK just recieved this one.It appears to be in OK condition.Has some problems which sem to be electrical in nature.At 18 and 24 fps,when the trigger is depressed,there is a 9 second delay before it runs.There is a knob missing on the intervalometer (time lapse control) so I'm assuming this delay has something to do with this.Also the knob on the auto/manual iris is missing and it's difficult to set the iris.Any techies out there to offer help?
