I was trying to shoot a long exposure with my DM22 back with HX-701 on RZ67 Pro IID! Obviously, I chose Mamiya RZ67 Pro IID from the menu on the back! I set the shutter on B and chose T on the lens as I always do when I shoot film! After 15 second, I pushed T to N mode! However, it did not work! No picture! I mean I could trigger the shutter but nothing happened to the back! I then set the shutter on 8 second and it worked!
Have any of you experienced this before!?
Do I need a sync cable? How can I do a long exposure on B mode!?
