Does anyone have experience with the Kapture Group HA-001? I want to use the focal plane shutter in my Hasselblad 2003FCW at speeds faster than 1/90 second (the sync speed). Their cable release seems to make my system compatible (Leaf-Aptus II 12R back and Hasselblad 2003FCW), and the current price is $295. Even if I purchase the Kapture cable release will I have a full image on the digital back? Any help will be greatly appreciated.
