70mm with RZ67

[k.hendrik]

Hi all,
Have a 70mm RB film holder with G adapter for my RZ67 Pro II; worked nicely untill last weekend. Film advance lever on the 70mm got stuck. I'm doing something wrong I think! What is in detail the procedure(settings camera and back!) for shooting with this combo. Thanks in advance.

"There is a little button at the centre upper rear of the back, above the memo-clip, just below the advance lever. You push it to the left to tell the back that an exposure has been made, and it releases the interlock on the advance mechanism" Problem solved.
