Hasselblad 503 CW with Winder CW
Please note that the Phase One P back should not be
mounted while the camera is set to mirror up.
Also make sure that the lens is not jammed or locked
open on the “B” setting when connecting the flash
sync cable to the Phase One P back.
If you are using a 503 CW winder you could set the
Shutter latency to ”Short latency”
